A Multistage Approach for Detection of Objects with Rectangular Forms

This paper proposes a multistage approach for detection of different objects with rectangular shape forms in real images. It consists of image enhancement, following by edge detection to suppress most possible false edges, and modification of Hough Transform. Peaks of the Hough image are extracted, and a rectangle is detected when these peaks satisfy certain geometric conditions. Some experimental results are given to illustrate the effectiveness of the proposed approach.
