METHODS AND SYSTEMS FOR DETERMINING A PERCEPTUAL SIMILARITY BETWEEN IMAGES

摘要

Systems, methods and computer program products for determining perceptual similarity between independent images are described. The described systems, methods and computer program products use a similarity distance to determine the perceptual similarity between a first image having a first arrangement of pixels and a second image having a second arrangement of pixels. A processor can determine a first image array corresponding to the first arrangement of pixels and a second image array corresponding of the second arrangement of pixels. The processor can generate a first pixel group set based on the first image array and a second pixel group set based on the second image array. A plurality of pixel group pairs can be generated, and each pixel group pair can be associated with a corresponding pixel group pair distortion. The similarity distance between the first image and the second image can be determined based on the plurality of pixel group pair distortions.
