A new automatic edge detection technique, based on combination of the good points of other common techniques, is introduced. The proposed technique produces edges and boundaries similar to the visual perception of a human observer. Thin and closed contours are produced due to the nature of the implemented detection of only one side of the zero crossing, and the proposed linking process. Number of false edges detected by our algorithm is much less than of other techniques. No image dependent parameters or threshold is used.
