Unit 1 · 5 hrs
Image Processing Basics: Fundamentals, Types, and ApplicationsUnit 1 of Image Processing introduces core concepts like digital image formation, types of images (grayscale, color, binary), image processing systems, and applications in real-world domains such as medical imaging, satellite remote sensing, and computer vision. This note covers definitions, workflows, and comparisons 5 min readUnit 2 · 8 hrs
Image Enhancement & Spatial Filters: Techniques, Filters & ApplicationsUnit 2 of Image Processing covers spatial-domain image enhancement techniques, including point operations (histogram manipulation), spatial filtering (linear/nonlinear), and their applications in real-world systems like medical imaging, surveillance, and digital photography.9 min readUnit 3 · 8 hrs
Image Restoration & Compression: Noise Removal, Deconvolution, JPEG, DCT, HuffmanUnit 3 of Image Processing covers techniques to reverse image degradation (restoration) and reduce file size (compression), including noise filtering, deblurring, transform coding (DCT), and entropy coding (Huffman). Learn how to mathematically recover lost details and compress images efficiently for web and storage.5 min readUnit 4 · 2 hrs
Morphological Image Processing: Erosion, Dilation, Opening, ClosingUnit 4 of Image Processing introduces morphological operations—erosion, dilation, opening, and closing—using structuring elements to modify image shapes, remove noise, and segment objects. Learn how these operations work, their mathematical foundations, and real-world applications in medical imaging, document processin10 min readUnit 5 · 8 hrs
Image Segmentation: Techniques, Thresholding, Clustering, Edge Detection & ApplicationsUnit 5 of Image Processing covers partitioning images into meaningful regions for analysis, including thresholding, clustering, edge-based, and region-based segmentation methods, their mathematical foundations, and real-world applications in medical imaging, autonomous vehicles, and object recognition.15 min readUnit 6 · 6 hrs
Image Representation, Description & Recognition: Features, Models & MatchingUnit 6 of Image Processing covers how to mathematically represent images (pixels, transforms), extract meaningful features (edges, textures, histograms), describe objects (shape descriptors, signatures), and recognize patterns (template matching, neural networks).
