| Abstract: | Through analysis to image bluring mechanism and the theorem of image debluring, convolution and deconvolution processes were converted into matrix operation and inverse resolution by means of Teoplitz method. The mechanism of Teoplitz was derived from one dimensional anti convolution process at first. And then Teoplitz method was extended into two dimensional operation. Then image bluring and debluring were realized by Teoplitz approach. Theoretic analysis and simulation show the correctness and accuracy of Teoplitz mehod. |
