Direct Blind Deconvolution II. Substitute Images and the Beak Method

November 1, 2000
Alfred S. Carasso
The BEAK method is an FFT-based direct blind deconvolution technique previously introduced by the author, and applied to a limited but significant class of blurs that can be expressed as convolutions of 2-D symmetric L vy probability density functions

Image Compression and Deblurring

May 1, 2000
Anastase Nakassis, Alfred S. Carasso
What follows is the description of an experiment in which we investigated the possibility that blurring techniques and lossless compression could be combined as an alternative to lossy compression techniques for still images. Our results show that while

Direct Blind Deconvolution

November 1, 1999
Alfred S. Carasso
Blind deconvolution seeks to deblur an image without knowing the cause of the blur. Iterative methods are commonly applied to that problem, but the iterative process is slow, uncertain, and often ill-behaved. This paper considers a significant but limited
