Image medium similarity measure and its applications

• Establish image medium similarity measures based on MMTD.
• Apply the medium similarity measure to image edge detection.
• Apply the medium similarity measure to image matching.
• Present an image medium fidelity measure method.

Similarity measure plays an important role in many image processing fields. This paper introduces the medium mathematic systems, and establishes a novel image medium similarity measure between two pixels and that of between two image sets based on the measure of medium truth degree. Moreover, an image edge detection algorithm, an image matching algorithm and an image medium fidelity measure method governed by the medium similarity measure are discussed in this paper. Experimental results show that the proposed similarity measure is effective.
