Abstract: Based on whole qualitative analysis, this paper compares and validates merits and demerits of various edge detection algorithms in a quantificational way from several typical judgement standards for edge detection algorithms like edge connectivity, nosie resistence ability, operation complexity. By means of B cubic spline interpolation, it improves the quality of the detected images. Experiental results show that this methods can be well applied in the region of image processing.
