A approach of depth recovery from defocused image based on wavelet multiresolution analysis is proposed. The Lipschitz exponent is used to describe the singularity of the edge of an object in image. A curve of relationship between Lipschitz exponent and the distance from interested object to camera is obtained. Experiment proved the effective of the method.
