WebJul 1, 2011 · Introduction Compressed sensing is a new data acquisition theory based on the discovery that one can exploit sparsity or compress- ility when acquiring signals of general interest, and that one can design nonadaptive sampling techniques that condense e information in a compressible signal into a small amount of data [13,16,18]. WebCompressed sensing (CS), introduced by Candès, Romberg & Tao [] and Donoho [], has been one of the major developments in applied mathematics in the last decade [10, 27, 26, 22, …
WebJan 30, 2015 · Aquatic debris monitoring is of great importance to human health, aquatic habitats and water transport. In this paper, we first introduce the prototype of an aquatic sensor node equipped with an embedded camera sensor. Based on this sensing platform, we propose a fast and accurate debris detection algorithm. Our method is specifically … Web2.2. Incoherence Compressed sensing is based on a choice of a sensing basis ˚relative to representation basis, which use an incoherence property for measure the correlation between vectors from each basis. The minimum correlation between any two elements of two di erent matrices is called coherence, it is denoted by (˚, ).
