Edge Detection with Sub-pixel Accuracy Based on Approximation of Edge with Erf Function
Edge detection is an often used procedure in digital image processing. For some practical applications is desirable to detect edges with sub-pixel accuracy. In this paper we present edge detection method for 1-D images based on approximation of real image function with Erf function. This method is v...
