Image processing method and device, equipment, storage medium and computer program product

The invention relates to an image processing method and device, computer equipment, a storage medium and a computer program product. The method relates to an artificial intelligence image processing technology, and comprises the steps that a to-be-recognized image is acquired, and the to-be-recognized image comprises biological characteristics of a to-be-recognized object; performing frequency domain transformation on the to-be-identified image to obtain a frequency domain graph comprising a plurality of frequency channels; combining high-frequency channels in the frequency domain graph to obtain a plurality of high-frequency channel groups; selecting a target high-frequency channel group from the plurality of high-frequency channel groups, and selecting a target channel replacement sequence from the candidate channel replacement sequences; performing channel sequence replacement processing on each high-frequency channel in the target high-frequency channel group according to a target channel replacement sequ
