Obtaining Chain Codes in Image Edge Detection
This code implements chain code extraction for image edge detection, where 'img' represents the input image, 'Array' stores the resulting chain codes, 'x0y0' contains initial point coordinates, 'xy' records the final point coordinates, and 'Ratio' calculates chain code curvature. The implementation uses boundary tracing algorithms to follow edge contours and generates directional codes (typically using 4 or 8-connectivity) representing edge segment orientations. Comment annotations explain the logic for international developers. Currently developing phase coding implementations - collaboration welcome for researchers interested in this domain.
