A Survey on Dynamic Compressed Sensing
摘要
Abstract
In video signal processing, dynamic compressed sensing (DCS) is a novel branch of compressed sensing (CS) theory for recovery of compressible, possibly with a slowly varying sparsity pattern, signal from a time sequence of noisy observations. Dynamic compressed sensing has been employed in dynamic magnetic resonance image reconstruction successfully. The system model for dynamic compressed sensing is first introduced, including definitions of slowly varying supports, sparse representations and stable measurement of the time-varying sparse signal. Then, a unified framework is formulated for reconstruction of the time-varying sparse signal. Based on the framework, classification is conducted for the existing algorithms whose main ideas, reconstruction procedures and performance are also commented briefly. Finally, the applications and future directions of dynamic compressed sensing are pointed out.关键词
