Description: 全变差图像处理Matlab程序，for the paper: "Algorithms and Software for Total Variation Image Reconstruction via First-Order Methods, Numerical Algorithms"-Software for Total Variation Image Reconstruction (for Matlab Version 7.5 or later)
"mxTV" is a software package for image reconstruction based on the Total Variation model, and including denoising, inpainting, and deblurring. The work was carried out as part of the project CSI: Computational Science in Imaging, funded by the Danish Research Council for Technology and Production Sciences, and headed by Prof. Per Christian Hansen, DTU Informatics. The collaborators are DTU Informatics, Dept. of Electronic Systems at Aalborg University, and MOSEK ApS.
The underlying algorithms are based on recently published first-order methods developed by Nesterov, tailored specifically to the image restoration problems. These methods have O(1/ε) complexity, where ε is the accuracy of the solution. The core computational routines are written in C, with a mex interface to Matlab. The algorithms and the software are described in the paper:

Description: The spatially adapted total variation method
subproblems are solved by a locally uperlinearly convergent algorithm based on Fenchel-duality and inexact semismooth-Newton techniques.
The SATV Toolbox was written in MATLAB. It implements:
1) image restoration with a scalar regularization parameter for
- Gaussian noise removal
- deblurring and Gaussian noise removal
2) image restoration with a spatially dependent parameter for
- Gaussian noise removal
- deblurring and Gaussian noise removal.

Description: FISTA
My implementation of an Fast Iterative Shrinkage Thresholding Algorithm on MATLAB. Based on the implementation discussed in:
Beck, Amir, and Marc Teboulle. Fast Gradient-Based Algorithms for Constrained Total Variation Image Denoising and Deblurring Problems - IEEE Xplore Document. N.p., 11 June 2009. Web. 20 Apr. 2017.
Beck, Amir, and Marc Teboulle. "A Fast Iterative Shrinkage-Thresholding Algorithm for Linear Inverse Problems." SIAM Journal on Imaging Sciences 2.1 (2009): 183-202. Web.
Project was done during BME593 - Computational Methods for Inverse Problems. The MATLAB functions and files starting with tp as well as project_test and ISTA_test were implemented by me. The data and other files were implemented by the TAs in the class.
To initiate the FISTA algorithm on the given data set, please run project_test.
The details of the implementation, as well as discussions of the technique can be found in project_writeup.pdf. Platform: |
