Computer vision is intended to make computers own the ability to understand the visual scene like human being. To this end, object detection is an important task. However, a difficult problem which hampers this task is the disturb of clutter objects in natural scenes.This thesis addressed the problem of detecting object based on an edge

Shape matching is to measure the similarity between two shapes with some rules. It is a fundamental problem in automatic image recognition and understanding, and is widely used in computer vision, pattern recognition, remote sensing image analyzing, handwriting recognition, etc. During the past few decades, many approaches have been proposed to tackle it. But there
