Abstract
The distributions of irradiance on the image plane decrease away from the center of the image even if the scene is a uniform white field. This crucial problem is posed in digital image processing, such as edge detection and stereo matching. This paper presents an edge detection method of non-uniform illumination image which uses fitting calibration algorithm to correct the non-uniformity and wavelet transform to extract edges from the images corrected. The experimental results demonstrated the validity of our theoretical model and the effectiveness of wavelet transforms based edge detection of non-uniform illumination image.
