Introduces the very sparse random projection into Compressed Sensing(CS) theory and presents a new kind of CS measurement matrix:very sparse projection matrix.By the asymptotic normality for very sparse random projection distribution,proves that the new matrix satisfies the necessary condition for CS measurement matrix.Owing to its sparsity of structure,new matrix greatly simplifies the projection operation during images reconstruction,which greatly improving the speed of reconstruction.The results of simul...
