        "abstract": "Compressed sensing (or Compressive sampling) tries to exploit the sparsity of signals to either improve\r\nthe quality of reconstructions, or reduce the required number of samples.\r\nThe samples are usually taken by multiplication with some matrix with independent — normally\r\ndistributed — random values, or by selecting values from the Fourier transform of a signal. Important\r\nis that the signal should not be sparse in the transformed domain. How many samples need to be\r\ntaken depend on the characteristics of the matrix and the signal.\r\nSeveral introductory texts, as well as a lot of reference material, can be found on\r\nhttp://www.dsp.ece.rice.edu/cs/.",
