摘要
The orientation accuracy of a general class of edge detection operator acting on binary and saturated grey-scale images is studied. An operator similar to the Sobel operator is found to have the best available accuracy, of about +/- 9.6-degrees, which is remarkably close to the figure of +/- 1.2-degrees for grey-scale images. In addition, performance necessarily degrades gracefully in the presence of noise.
