Traditional edge detection algorithms often struggle to establish appropriate thresholds for detecting faint edges with low gradient values in certain images. This implementation addresses this issue through two enhanced approaches: image variance normalization to amplify gradient values of blurred edges, and sigmoid function integration to incorporate regional pixel information into gradient calculations for threshold optimization. The program compares these advanced techniques with conventional edge detection methods, providing comprehensive performance evaluation through practical algorithm implementations using gradient computation and adaptive thresholding.
