On the design of a sparsifying dictionary for compressive image feature extraction
(Institute of Electrical and Electronics Engineers, 2015)
Compressive sensing is an alternative to Nyquist-rate sampling when the signal to be acquired is known to be sparse or compressible. A sparse signal has a small number of nonzero components compared to its total length. ...
