To ensure the location accuracy of edge and minimize false edge points produced by noise and uneven gray scale in image is a difficult problem for edge detection. A new multi-scale tensor algorithm is presented to detect image edge. This method could obtain richer partial structure information in different scales. It is proved to be efficient in precision edge detection and noise suppression by experiments.
