...3(d) has the advantages of the low coherence of the Fourier-wavelet basis at coarse scales, where the signal tends to be less sparse, and the universality of the Gaussian random projections sensing [17] in fine scales, where the signal tends to be more sparse....

...VARIABLE DENSITY SUB-SAMPLING OF THE FRESNEL TRANSFORM The motivation for the variable sampling density scheme appears evident from the examination of the effect of the Fresnel transform on the joint spatial-spatial frequency distribution (phase-space distribution) of the object field....
