Jaya Tiwari, Rajesh Kumar Rai, Brahmi Shrman . A Review on Estimation of Defocus Blur from a Single Image. International Journal of Computer Applications. 106, 1 ( November 2014), 46-49. DOI=10.5120/18488-9552
Defocus estimation is an important part in high quality image processing field, which mainly includes edge detection, image deblurring, and measuring image quality. Wrong lens setting or shallow depth of field which would produce defocus blur. Defocus blur is most of the times present in natural images. In this paper we have discussed some of the methods like local contrast prior, defocus magnification and spectrum contrast for estimating the defocus blur map.
