The invention discloses an image processing method based on group-wave transformation compressed sensing. The method specifically comprises the steps that orthogonal group-wave transformation is carried out to an image at first, so that sparsity coefficients in each directional scale are obtained; then high-frequency coefficients of each scale are compressed, measured and encoded; and finally, orthogonal group-wave inverse transformation is carried out to stored low-frequency coefficients and recovered high-frequency coefficients, so that a recovered image is obtained. The method has the advantages that sparse representation of group-wave transformation is fully integrated into the compressed sensing; image geometrical characteristics are utilized to the hilt; redundancy and resource waste caused by traditional Nyquist sampling theories are eliminated; texture information such as directions and scales of images can be further excavated; and high-definition images can be recovered when only a few of sampling points can be provided. In comparison with the existing method of wavelet transformation compressed sensing, the method disclosed by the invention has obvious advantages and has very broad application prospect in image processing.
