ABSTRACT:
A method for automatically cropping image objects, including: an object contour detecting step, an image dividing step, and an image merging step. The object contour detecting step detects object contours with Modified Laplacian Contour Detector to generate a binary image. The image dividing step divides the binary image into a background region and a plurality of non-background regions with Connected Components Algorithm (CCA). The image merging step merges the closer non-background regions from large to small, and determines whether the merging is reasonable for cropping the image object.
