Abstract
Image edge detection is one of the important contents of image processing. In this paper, we show a new edge detection operator, which is Log_Sobel. This operator processes image with logarithm of luminosity (luminous density) not with luminosity. It processes fast, and suits online detection. What's more, the detect result is in dependent of luminosity. At the same time, it is applied to the online detection. The experiment results show that the effect for image processed by Log_Sobel operator is better than those operators, including Roberts algorithm, Prewitt algorithm and Sobel algorithm, proposed by predecessor.
