基于分块可压缩传感的图像重建

============================================================================== BCS-SPL Version 1.2, 09-aug-2009 Copyright (C) 2009 James E. Fowler ============================================================================== OVERVIEW: These MATLAB programs implement the Block Compressed Sensing - Smoothed Projected Landweber (BCS-SPL) algorithm as described in paper: S. Mun and J. E. Fowler, "Block Compressed Sensing of Images Using Directional Transforms," submitted to the IEEE International Conference on Image Processing, 2009 Specifically, this code reproduces the experiment results of the paper (Table 1), for the BCS-SPL-CT, BCS-SPL-DDWT, BCS-SPL-DWT, and BCS-SPL-DCT algorithms. Respectively, the code for these is: run_experiment_ct.m run_experiment_ddwt.m run_experiment_dwt.m run_experiment_dct.m This code relies on the Contourlet Toolbox (http://www.ifp.illinois.edu/~minhdo/software/) as well as the Wavelet Software package (http://taco.poly.edu/WaveletSoftware/). Both will need to reside within the current MATLAB search path. Note that, since most of this code relies on random projections, the results produced may differ slightly in appearance and value from those of the paper. ============================================================================== AVAILABILITY: For updated versions of BCS-SPL, as well as the article on which it is based, consult: http://www.ece.msstate.edu/~fowler/ ============================================================================== COPYRIGHT AND LICENSE INFORMATION: Copyright (C) 2009 James E.
