Contrast enhancement of X-rays, tumor detection in MRI/CT scans, and automated cell counting.
Machine vision systems for automated sorting, quality control, and robotic assembly inspection. 5. Summary Matrix of Core Algorithms Algorithm / Process Primary Purpose Key Benefit Histogram Equalization Spatial Domain Contrast Improvement Uniformly distributes image intensity Median Filtering Spatial Domain Noise Reduction Effectively removes salt-and-pepper noise Discrete Cosine Transform Frequency Domain Data Reduction Compresses image energy into few coefficients Canny Edge Detection Spatial Domain Feature Extraction High localization accuracy with low false positives Otsu's Method Segmentation Image Thresholding Automatically calculates optimal grey-level threshold

Beyond grayscale, the slides covered color transformations, enhancement, and segmentation:
Conceptually shifting an image from the spatial domain to the frequency domain using 2D Discrete Fourier Transforms (DFT). Summary Matrix of Core Algorithms Algorithm / Process
Expanding dark pixels and compressing bright pixels (
For students and faculty alike, the search for the accompanying has become a rite of passage. These presentations are not merely summaries; they are structured pedagogical tools designed to decode topics like image transforms, enhancement, restoration, and compression.
Unlike enhancement, restoration seeks to reconstruct or recover an image that has been degraded by using an a priori knowledge of the degradation phenomenon. Gaussian, salt-and-pepper, and impulse noise.
