This technique can find the edges in high noised images; it is calculated using first-order fractional derivative and cross-gradient operator (Eqs. A vector is described as a wrinkled and a bent object that is defined precisely by the computer. There are many other technologies used to record information about the location and function of the body. Segmentation process of (a) thyroid gland and heart [3]. The fluoroscopy system is used to scan the moving organs. Pixel is the term most widely used to denote the elements of a digital image. There are many muscles surrounding the eye and that control the widening of the pupil. Medical imaging is the procedure used to attain images of the body parts for medical uses in order to identify or study diseases. (1)). Using the tool processing more medical images of human organs are (Brain, Lung, Kidney, Skin, Retina, Finger, Tissues and Skull). The objective of segmentation is the partition of the images into important portions. Signal-to-noise ratio (SNR) calculates from the image in an up-front method. Medical Image Processing Projects are developed based on image processing simulation tool named as Matlab. (8) [15, 16]: This technique can be dependent on the central difference which tends toward the central pixels in average. This technique is calculated as shown in Eqs. Ultrasound is similar to the location determination technique, which is used by some animals like bats and whales in the nature. This includes algorithms, such as ANIMAL, for linear and non-linear image registration as well as template building. Microcomputerized on-line image processing systems and a compound sector scan echocardiography using two probes developed for echocardiographic examinations are shown with some results in clinical applications. Brief introduction to this section that descibes Open Access especially from an IntechOpen perspective, Want to get in touch? Those techniques have many limitations compared to those modulates which produce images. Image registering and fusion methods are widely used nowadays specially in new modalities such as PET-CT and PET-MRI. Moreover, 3-dimensional functional images of the left ventricle are shown as well. The eyes are 2.5 cm in both crosswise and lengthwise diameters. Licensee IntechOpen. The histogram is the simplest image processing technique. This technique is also used to trace the objects’ borders within the images. In the 1970s with the development of computer system, the cost of image processing became less and faster. This process pursues the disorder identification and management. Thresholding segmentation uses the histogram and threshold value of pixels. Image color can be used as the basis for entire EM spectrum, ranging from gamma to radio extracting features of interest in an image. Signal-to-noise ratio (SNR) of an image is used to associate the level of the anticipated signal to the level of the contextual signal. The computer system uses the arithmetic and logic calculation to form the 2D image of the scanned structures. However, effects from current trends in the Medical Device Directives that increase the efforts needed for clinical trials of new medical imaging … The image segmentation technique is used to create 3D contour of the body for clinical purposes. The book is designed for end users in the field of digital imaging, who wish to update their skills and understanding with the latest techniques in image analysis. Those images were produced using fast processors and due to conversion of the energies arithmetically and logically to signals [2]. © 2019 The Author(s). Case Study: Image Processing. The area of medical image analysis and processing represents a very broad concept and every photonic technique requires adapted image analysis routines. Any intensity above or below makes the image darker or brighter. The digital images include many formats such as BMP (Windows bitmap), TIFF (Tag Interleave Format), PCX (Paintbrush), PNG (Portable Network Graphics), etc. This technique is better than Roberts operator (Figure 11). Medical imaging is the process of producing visible images of inner structures of the body for scientific and medicinal study and treatment as well as a visible view of the function of interior tissues. The mean value of central pixel intensity is designated to the ideal brightness. The electrons hit the anode to produce the X-rays. Gxand Gyare the calculations at [i, j]. This process includes both organic and radiological imaging which used electromagnetic energies (X-rays and gamma), sonography, magnetic, scopes, and thermal and isotope imaging. The 2D and 3D images can be processed in multiple dimensions. Digital image is composed of a finite number of elements, each of which has a particular location and value. The planar emission produces 2D images. This processing includes many types of techniques and operations such as image gaining, storage, presentation, and communication. With the growth of different image resizing techniques, the images can be kept efficiently. The acquired images can be displayed, stored, and communicated through different machines. The digital images lose their quality in the resizing process due to some missing data. Each pixel has a specific position and value. Those parts represent the entire original image and acquire its characteristics such as intensity and similarity. MIPAV, an acronym for Medical Image Processing Analysis and Visualization, is n-dimensional, platform-independent, and can process data originating from most medical imaging modalities, The program functions both as an end-user application and an Application Programming Interface (API) that can be used to develop other image processing, registration, and visualization applications. According to the modality results the physician can easily observe the pathologies directly but sometimes it took more time to analyzing. Local segmentation deals with the partition of the images into small parts within the images. HeadquartersIntechOpen Limited5 Princes Gate Court,London, SW7 2QJ,UNITED KINGDOM. Forensics matches the input data (fingerprint, eye, photo, etc.) Ultrasound is transmitted in high-frequency pulses into the body using a transducer as those waves travel through the body tissues. The range of potential difference used is 15–40 kV (Figure 3) [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16]. (9)–(12) [20, 21, 22]: The Sobel is better than Prewitt in noise reduction [18]. The image-gaining instrument controls the resolution. Assume that matric has arrangement of pixels [i, j] as in Eq. 3-dimensional reconstruction methods of the left ventricle and other organs from multiple 2-dimensional images are shown with 3-dimensional shapes reconstructed from images by x-ray, ultrasound and radionuclides. Yousif Mohamed Y. Abdallah and Tariq Alqahtani (June 24th 2019). (2)): The adaptive or fixed threshold segments image faster if the region of interest contains unique intensity and is different from the background. It can be achieved by a fiber optical scrambler spatially stabilizing the illumination intensity profile Kam et al., 1993). The mean pixel value is obtained from the histogram by summing the produced pixel values and consistent bin altitude and dividing by the entire number of pixels [7, 8]. These applications are based on one or more of the “multi” concepts that we have addressed in this review. The global threshold (θ) calculates using binarization procedure as in the following equation (Eq. The common techniques used in this field are edge detection, pattern matching, denoising, security, and biometric purposes such as identity, face, and fingerprint documentation. The vector has many qualities such as line width, dimension, and hue. To date our community has made over 100 million downloads. There are three types of thresholding methods. Raster image is described as a four-sided arrangement of frequently sampled values known as pixels. In pattern recognition, image processing is used for identifying the objects in an images and then machine learning is … Our readership spans scientists, professors, researchers, librarians, and students, as well as business professionals.

Digital Image Processing has a broad spectrum of applications. k-means clustering tends to find clusters of comparable spatial extent. (12) and (13)) [16]. (3) and (4)) (Figure 11) [21]. The gray-level histogram shows whether an image is generally shady or bright (Figure 5). Signal-to-noise ratio (SNR) is defined as the ratio of signal intensity to noise intensity. Given a set of comments (x1, x2, …, xn), where each comment is a d-dimensional actual vector, k-means clustering aims to subdivide the n observations into k (≤ n) sets S = {S1, S2, …, Sk} so as to minimize the within-cluster sum of squares (Eqs. Those signals later are converted to digital images. The human visual system is one of the most complex schemes that ever existed. computer and image technology medical imaging has greatly influenced medical field. The fractional derivative can be applied into two 2 × 2 matrices. The reflected waves are received by the transducer and converted into electric signals.

Image analysisincludes all the steps of processing, which are used for quantitativemeasurementsaswell asabstractinterpretationsofbiomedical images.These steps require apriori knowledgeon the nature and content of the images, which must be integrated into the algorithms on a high level of abstraction. This technique has a fewer number of pixels compared to the global type. The digital images play a necessary role on a daily basis. In the X-ray machines, the images are produced in 2D plans of the examined part of the body. Medical image processing: A review ... in analysis methods and computer-aided diagnosis has boosted medical imaging into one of the most important sub-fields in scientific imaging Ultrasound, MRI, CT-Scan, PET Scan are the medical techniques mainly used by the radiologist for visualization of internal structure of the human body without any surgery. However, unlike humans, who image processing involves the study of fundamental are limited to the visual band of the electromagnetic concepts in color models and basic color processing in a (EM) spectrum, imaging machines cover almost the digital domain. This technique has many sets of rules to perform into the images synchronously. The histogram is a scheme showing the pixels’ values and not their locations. This affects the interpreting processes and makes them difficult to diagnose by the physician. The local segmentation works particularly in one subdivision of the image. Help us write another book on this subject and reach those readers. Threshold method is useful for establishing the borders of solid objects in a dark background. These steps require a-priori knowledge on the nature and content of the images, which must be integrated into the algorithms on a high level of abstraction. Pattern recognition involves study from image processing and from various other fields that includes machine learning (a branch of artificial intelligence). X-rays accompany a screen covered with a storage phosphor device. Those electric signals are converted into digital ones and pass through the computer system. By making research easy to access, and puts the academic needs of the researchers before the business interests of publishers. The majority of new technologies, however, need further evaluation in large and controlled clinical trials to establish their medical and economic benefits. In this situation, Roberts masks are calculated as in Eq. These elements are referred to as picture elements, image elements, and pixels. As the quality of medical imaging affects diagnosis the medical image processing has become a hotspot and the clinical applications wanting to store and retrieve images for future purpose needs some convenient process to store those images in details. This technique identifies the discontinuity of the objects. There are many other techniques applied in radiology in order to rebuild or reslice the images such as Otsu’s and k-means techniques [5, 6]. This technique can be expressed as 3 × 3 matric to the first derivative of Gaussian kernel. Medical imaging produces the images of the internal structures of the body without invasive procedures. This technique is used in the functional imaging modality such as nuclear medicine. Computer-aided diagnostic processing has already become an important part of clinical routine. Digital image processing with the development of computer technology has been widely used in various fields, and the medical field is no exception. Since the discovery of X-rays by the German scientist Roentgen, X-rays have been used to image the body parts for diagnostic purposes. The book emphasizes the conceptual framework of image analysis and the effective use of image processing tools. Transform in digital image processing When c equals 1, the Prewitt operator is calculated as in Figure 10 and Eq. In this modality, the images are produced in multiple dimensions rather than the conventional radiography. The patient’s emitted photons are received in the detectors and convert into signals. In the 2000s, the image processing became quicker, inexpensive, and simpler [4]. Some of those waves are absorbed and some reflect back. IDL has a suite of processing routines and display methods that can be used for medical image processing and analysis. Computed radiography (CT) uses image receptor to produce the image. The human eye is bilateral cylinder structures that are located anteriorly in the skull. The disadvantage of this method is its simplicity and inability to process the multichannel images [15]. The mean intensity of the image is expressed as the square of the mean of the pixel value (Eq. Medical imaging is the procedure used to attain images of the body parts for medical uses in order to identify or study diseases. Copyright © 2021 Elsevier B.V. or its licensors or contributors. This technique is used in economical, stargazing, cultivation, and computer perception (Figure 13) [17, 18, 19]. image processing can process medical images, improve its quality, enhance the visual effects, hence, the true situation can be showed clearly. The shape of the lens changes continuously due to muscle contraction [4, 5]. This technique subdivides the image into n parts and into k clusters in which each observation fits to a cluster with a similar mean. In image processing, image enhancement and smoothing tools are used for medical image processing to improve the quality of images. This technique has more pixels to manipulate. Domain : Image Processing. Images consist of various small elements called pixels. Red blood cell segmentation using edge detection: (a) original image and (b) Sobel and (c) Prewitt techniques.
