A quantitative analysis on the local precision and the ability against noise for image edge detection with wavelets (IEDW) has been done in this paper. With an appropriate wavelet function, IEDW algorithm is equal with a process that consists of two child processes: denoising and edge detecting. The feature is relative to the type of edges and the scales. The influence of the scale is a morror of the local feature of wavelet transform.
