An adaptive parameterized block-based singular value decomposition for image de-noising and compression
We propose an adaptive parametrized block-based singular value decomposition (APBSVD)
for preserving the edge structure and avoiding blurred image after the compressing process.
We also exploit a proper selection of the Peak Signal to Noise Ratio (PSNR) parameter
at each block to appropriately eliminate high-frequency noise. Our numerical results show
that the proposed methods are promising which effectively remove the noise, and preserves
the edge information well during the block-based SVD image compression
