图像处理,压缩感知中ROMP的代码实现。
代码片段和文件信息
%应一个朋友的约,贴一个ROMP的代码
function [vOut numIts] = romp(n Phi x)
% [vOut] = romp(n Phi x)
%%% PARAMETERS %%%%%%%%%%%%%%%%%%%%%%%%%%%
% d = ambient dimension of the signal v
% N = number of measurements
% n = sparsity level of n
% Phi = N by d measurement matrix
% x = measurement vector (Phi * v)
% vOut = reconstructed signal
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%% FUNCTION DEscriptION %%%%%%%%%%%%%%%%%
% romp takes parameters as described
% above. Given the sparsity level n and
% the N by d measurement matrix Phi and
% the measurement vector x = Phi * v romp
% reconstructs the original signal v.
% This reconstruction is the output.
