Small-block sensing and larger-block recovery in block-based compressive sensing of images

作者：

Highlights：

• ACS scheme employs different block sizes in the sensing and the recovery.

• The scheme is analyzed with mutual coherence and compressibility of transform signal.

• The scheme achieves both low sampling cost and more-favorable recovery performance.
