EBM 503: Digital Image Processing Continuous Assessment Test 1

Continuous assessment test one in digital image processing, nine questions. Two commonly used imaging systems with their operation explained; what a digital image processing system is, the operations carried out within it and its diagram; the cross-disciplinary nature of the subject with two of its applications outside medical imaging; the brightness response of the human eye compared with that of photographic film; image formation in mammography, its key applications and the imaging techniques that can complement it; why the low megahertz range is used in ultrasound imaging; the definitions and role in image processing of the grey-level histogram, dynamic range and contrast, entropy, and signal-to-noise ratio; two operations common in image enhancement in the spatial domain; and the filters used to enhance images on social media, with how the equivalent is achieved in the frequency domain.
