摘要：Defocusestimation is an important part in high quality image processing, which includesedge detection,image deblurring,and measuring imagequality.Wrong lens setting or shallow depth of fieldwhich would producedefocus blur. Defocus blur is most of the times present in natural images.In this paper we have discussed some of themethods likelocal contrast prior, defocus magnification and spectrum contrast forestimating the defocus blur map.
