Image restoration method and device, equipment, storage medium and program product

Abstract

The invention provides an image restoration method and device, equipment, a storage medium and a program product, and relates to the technical field of image processing. The method comprises the following steps: acquiring a compressed color image; generating a quaternion observation vector according to the compressed color image; constructing a color image restoration algorithm based on a quaternion Cauchy estimator; and recovering the quaternion observation vector according to a color image recovery algorithm based on a quaternion Cauchy estimator to obtain a recovered image. The method is used for accurately reconstructing a restored image from a compressed color image.
