Optimization Method for Compress Sensing Projection Matrix Based on Discrete Wavelets Datums
Projection matrix is the important part of compress sensing.A new optimization method for Projection matrix based on discrete wavelets datums is proposed.According to characteristics of DWT coefficients,build a optimization projection matrix,Improve the sampling efficiency and Reduce the mutual coherence of column vectors.The experiment simulation can expedite the quality of reconstructed image,especially in conditions of low sampling rate,effect is more pronounced.And the experiment prove that the optimized projection matrix is satisfied the RIP condition.
