Other AbstractWhen the images compressed by traditional transformation compression algorithms are transmitted over wireless channels, if Gaussian random interference causes the loss of the crucial transformation coefficients, the contents of the reconstructed images will be lost obviously and this will reduce the accuracy of the subsequent detection and recognition results greatly. In order to solve this problem, based on the characteristics of equal importance about each compressed sensing component, this paper first analyzes the feasibility of resisting the interference by removing the distorted compressed sensing signal components, then proposes an anti-interference image reconstruction algorithm. This algorithm first confirms the new compressed sensing signals and the new reconstruction matrix based on the locations of the corresponding compressed sensing signal components of the Gaussian-interfered bits, and then reconstructs the original images employing the iterative threshold algorithm. The simulation results demonstrate that our algorithm can reconstruct exact images at low bit error rates, and inexact images whose qualities are slightly lowered without loss of local contents at high bit error rates. As a result, our algorithm can overcome the deficiency in anti-interference ability of transformation compression algorithms and the iterative threshold algorithm, thus proposes a feasible scheme for the anti-interference problem that arises in wireless image transmission.
