Image Edge Detection Using Wavelet Transform
Edge detection is a fundamental technique in digital image processing, designed to isolate the boundaries of objects within a scene. These boundaries typically correspond to regions where significant fluctuations in pixel intensity or color occur, providing critical information for object recognition, structural analysis, and texture categoriza ...
