Defocus Blur Detection and Estimation from Imaging Sensors

Defocus Blur Detection and Estimation from Imaging Sensors

Sparse representation has been proven to be a very effective technique for various image restoration applications. In this paper, an improved sparse representation based method is proposed to detect and estimate defocus blur of imaging sensors. Considering the fact that the patterns usually vary rem...
