Embodiment Construction
[0030] In order to express the embodiments, significance and advantages of the present invention more clearly, the present invention will be described in more detail below in conjunction with the accompanying drawings and comparison diagrams of reconstruction effects.
[0031] figure 1 It is an algorithm flow chart of forward and backward matching and tracking based on compressed sensing fusion proposed by the present invention. The specific flow of the algorithm is as follows:
[0032] (1) Input: perception matrix Φ, measurement value y, forward step size α, backward step size β 1 and beta 2 , the maximum limit parameter K of the support set max , residual energy termination parameter ε, support set retention control parameter η;
[0033] (2) Initialization: initial support set initial residual r 0 = y, the initial number of iterations k = 0;
[0034] (3) The perception matrix Φ, the measured value y, the forward step size α, and the backward step size β 1 and the emp...
