Abstract : It combines dual-channel edge detection (Canny and Sobel), density-adaptive morphological structuring element selection, watershed-based object separation, and a seven-criterion shape filter to detect and count objects in urban surveillance images. The proposed approach is evaluated and compared against two segmentation-based baseline methods [1][2], demonstrating the advantage of density-adaptive parameter selection over fixed-parameter classical schemes. A proof-of-concept evaluation on two real urban surveillance images yielded object counts of 27 and 24, with complete pipeline telemetry confirming the density-adaptive feature.

Keywords : Adaptive Morphological Refinement, Edge Detection, Object Counting, Smart City, Canny Operator, Sobel Gradient, Watershed Segmentation, Connected Components, MATLAB.
