We propose to apply phase-only filtering (POF) to define the compression matrix for compressive sensing.
- class="label">•
This choice is motivated by that the POF matrix is always unitary and POF-filtered images are usually sparse.
- class="label">•
Lasso recovery of a POF-filtered images is very fast and can be used at extreme compression rates.

Experimental pattern recognition results obtained with a single-pixel camera are reported.
