Edge detection is one of the fundamental computer vision tasks. Recent methods for edge detection based on a convolutional neural network (CNN) typically employ the weighted cross-entropy loss. Their predicted results being thick and needing post-processing before calculating the optimal dataset scale (ODS) F-measure for evaluation. https://safeersappliancers.shop/product-category/rangemaster-leihdc110sc-built-in-110cm-3-speeds-e-chimney-cooker-hood-stainless/
