Method and system for determining similarity between images using pair-wise divergence matrix

A system for determining similarity between images using a pair-wise divergence matrix, the method comprises:

• a processor;
• and
• a memory communicably coupled to the processor, wherein the memory stores processor-executable instructions, which when executed by the processor, cause the processor to:
• compute a pair-wise divergence value of each patch of a first image relative to each patch of a second image using an F-divergence method selected from a plurality of F-divergence methods, wherein the pair-wise divergence value is computed using a probability distribution of each patch of the first image relative to each patch of the second image;
• create a pair-wise divergence matrix based on the computed pair-wise divergence values of each patch of the first image relative to each patch of the second image;
• and
• calculate a similarity score between the first image and the second image based on the pair-wise divergence matrix.
