Objectives of the Course The purpose of this course is to introduce some mathematical basics to remove blur of images and use MATLAB software to remove blur of images. In this lesson, after getting familiar with some concepts of image processing and the reasons for the existence of blur in images, students will solve image deblurring using mathematical methods that are mainly based on linear algebra.
Course Content The Image Deblurring Problem, A First Attempt at Deblurring, Deblurring Using a General Linear Model, Manipulating Images in MATLAB, The Blurring Function: Obtaining the PSF, Noise, Boundary Conditions, Structured Matrix Computations: 1D and 2D Problems, BCCB Matrices, BTTB + BTHB+BHTB + BHHB Matrices, Kronecker Product Matrices, Creating Realistic Test Data, Introduction to Spectral Filtering, SVD Analysis, The SVD Basis for Image Reconstruction, The DFT and DCT Bases, The Discrete Picard Condition, Regularization by Spectral Filtering, Implementation of Filtering Methods, Regularization Errors and Perturbation Errors, Color Images, A Blurring Model for Color Images, Tikhonov Regularization Revisited, Working with Partial Derivatives.
