Abstract

The invention discloses a binocular visual image super-resolution fusion de-noising method, comprising steps of (1) inputting a binocular image to be subjected to super-resolution fusion, (2) performing global position image registration, (3) performing local position image matching, (4) updating the binocular image, (5) performing image super-resolution fusion, (6) performing image de-noising, and (7) outputting a final high resolution image. In the image registration process, a local position registration method is added, a Laplace operator is applied to the image super resolution fusion, and a non-local mean value filtering method is employed to perform de-noising on the fusion image. The binocular visual image super-resolution fusion de-noising method overcomes the deficiencies in the prior art that image local positions are not matched, detail enhancement is not enough and the function of noise inhibition is absent. The binocular visual image super-resolution fusion de-noising method obtains a super resolution fusion image which has enhanced image details and reduced noise.

Description

technical field [0001] The invention belongs to the technical field of image processing, and further relates to a binocular vision image super-resolution fusion denoising method in the technical field of image super-resolution. The present invention can be applied to image post-processing of intelligent terminal equipment or professional camera equipment. Background technique [0002] The image super-resolution fusion method of binocular vision refers to the left grayscale image and right grayscale image of the same scene obtained from the binocular camera, using their temporal and spatial correlation and information complementarity, using reconstruction technology Image super-resolution fusion. The reconstruction technology assumes that the super-resolution image is under appropriate deformation, translation, sub-sampling and noise interference, and uses multiple frames of low-resolution images as data consistency constraints, and combines image prior knowledge to solve th...
