Image processing or digital image manipulation is one of the greatest advantages of digital radiography (DR). Preprocessing depends on the modality and corrects for system irregularities such as differential light detection efficiency, dead pixels, or dark noise. Processing is manipulation of the raw data just after acquisition.

European Radiology, 1997
The image quality of a radiograph is determined by the local contrast, spatial resolution, latitude and the image noise. The goal of digital processing is to improve the visualisation of pathology by optimising these physical parameters. Processing parameters need to be chosen correctly in order to overcome the inverse relationship between contrast and

Digital Processing of Diagnostic Images [PDF]
, 2010 In the Chapter different measurement systems for medical diagnosis are described. Different kinds of diagnostic images are exploited: ultrasound images for carotid analysis, epiluminescence microscopy (ELM) images for skin lesion diagnosis, and mammograms for breast cancer diagnosis.

Face Detection and Recognition System using Digital Image Processing
International Conference on Innovative Mechanisms for Industry Applications, 2020While recognizing any individual, the most important attribute is face. It serves as an individual identity of everyone and therefore face recognition helps in authenticating any person's identity using his personal characteristics.

Image processing in digital radiography
Seminars in Roentgenology, 1997Image processing is a critical part of obtaining high-quality digital radiographs. Fortunately, the user of these systems does not need to understand image processing in detail, because the manufacturers provide good starting values. Because radiologists may have different preferences in image appearance, it is helpful to know that many aspects of ...

Digital processing in cardiac imaging
The International Journal of Cardiac Imaging, 1985In recent years, imaging modalities have realized the potential for digitizing images of the heart. These modalities include nuclear cardiology, echocardiography, digital subtraction angiography, computed tomography, positron emission tomography, and magnetic resonance imaging.

Metric Aspects of Digital Images and Digital Image Processing. [PDF]
, 1984 Abstract : The ability of human pointing in digitized aerial imagery is studied. Automated methods for extracting edge locations in digital imagery are determined with subpixel accuracy. An algorithm for automatically extracting cross targets from aerial imagery is developed and implemented.

Concrete Crack Assessment Using Digital Image Processing and 3D Scene Reconstruction
Journal of computing in civil engineering, 2016Traditional crack assessment methods for concrete structures are time consuming and produce subjective results. The development of a means for automated assessment employing digital image processing offers high potential for practical implementation ...

Digital image processing of confocal images
Image and Vision Computing, 1983In a confocal imaging system, the image is built up point by point and is therefore well suited for image digitization and processing. A confocal system also allows range information to be obtained which facilitates an understanding of the 3D ·structure of the object.

Introduction to Digital Image Processing [PDF]
, 1991 Along with sounds, images are one of the most important means human beings use to communicate with each other. Recent efforts enlarge this communication even to machines. Image processing is the ensemble of methods which make this operation possible, simplier, more efficient and more pleasant.
