Abstract

A method of processing a motion blurred image from an imaging device to recover a latent sharp image. The method includes capturing a motion blurred image signal through the imaging device, computing a second signal as a two-dimensional wavelet transform of the motion blurred image signal, and using the second signal to perform a first autocorrelation analysis to estimate the blur kernel. After estimating the blur kernel, a local autocorrelation analysis yields a blur kernel length and direction at each pixel location of the motion blurred image. In addition, the second signal is denoised and the discrete wavelet transform coefficients reconstructed from the blur kernel length and direction. Performing an inverse discrete wavelet transform of the discrete wavelet transform coefficients recovers the latent sharp image.
