Multi-scale Mathematical Morphology Based Image Edge Detection

Edge detection is one of the most challenging tasks in image processing. A scheme for edge detection of images based on multi-scale morphology is presented in this paper. Mathematical morphology is a mathematic tool to analyze the image based on the structuring element. The morphological edge detection operator is non-linear difference operator. The results due to the proposed method have been found reasonably satisfactory. It proves that a morphological operation with a scalable structuring element can extract features more exactly.
