ABSTRACT:
A method for detecting edges in an image is disclosed along with corresponding apparatus and system for accurately extracting edges in the image. The edge detecting apparatus comprises a reading means, an image gray-level statistical means, an image classification means, a segmenting threshold generating means, an edge criterion determining means, and an image edge extracting means. The present invention realizes a reliable and accurate method for detecting edges in an image so as to extract edges in various file images.
