PROJECT PROPOSAL

We propose to research Image Restoration through three steps:

1. Get familiar with the WIENER2 command in MATLAB in order to understand simple denoising of images.

2. Investigate inverse filtering to remove the effects of degradation.

a) Use known LSI degradation model H and thresholding to perform Wiener filtering on image. Try both FIR and IIR Wiener filters.

b) Compare with blind deconvolution methods for obtaining H.

3. Try some wavelet domain deconvolution approaches with known H.


The focus of the project will be to investigate steps 2b) and 3), if time permits. We have some references on blind deconvolution and wavelet deconvolution (see REFERENCES) that we are currently perusing. We hope to gain some insight into Wiener filtering applications and blind convolution in the course of our experiments.
