Defect detection of ICT images and DR images is to locate the defects of workpiece in images and get defects’geometric parameters information as accurate as possible.

A novel DR image denoising algorithm based on Laplace-Impact mixture model in dual-tree complex wavelet domain is proposed in this paper.
