Abstract: Color edge detection based on CNN has attracted many researches. Most existing works utilize fixed threshold based on experience to design CNN templates. However, this method ignores the fact that the human vision system has strong adaptability. Adaptive thresholds are brought into the progress of designing CNN templates, which consider high adaptability of human vision system. Meanwhile, the stability of this algorithm is comprehensively discussed. The algorithm is able to make detected edges be more acceptable by the human vision system. Performance evaluation results validate the efficiency of the proposed algorithm.
