Many applications in picture processing.require accurate slope estimation. A brief survey of these applications is followed by discussion of the Sobel edge detection operator. The Sobel operator is very fast and simple; however, it is inherently biased as a function of true slope value and displacement of the true edge from center of the processing.window. An iterative version of the operator is presented which reduces this bias with only a moderate increase in required processing.
