Claim 19:
20. A non-transitory computer-readable storage medium, storing a computer program, wherein when executed by a processor, the computer program is configured to:
perform sparse representation on a target image by using an initial sparse matrix to obtain an initial sparse representation result;
quantify the initial sparse representation result to obtain an optimized sparse representation result, and optimize the initial sparse matrix according to the optimized sparse representation result to obtain an optimized sparse matrix;
construct a product matrix by using the optimized sparse matrix and an initial measurement matrix, and adjust absolute values of off-diagonal elements in the product matrix to be less than a correlation threshold;
perform singular value decomposition on the adjusted product matrix to obtain a diagonal matrix and a left singular matrix, and update the diagonal matrix according to a quantity of samplings of the initial measurement matrix; and
optimize the initial measurement matrix by using the left singular matrix and the updated diagonal matrix to obtain an optimized measurement matrix, and collect image data by using the optimized sparse matrix and the optimized measurement matrix.
