Abstract

The invention provides an objective evaluation method and a system for the quality of an infrared polarization image. The method comprises the following steps of S1, acquiring an infrared polarization image based on a target detection visual task, establishing an image definition evaluation model based on a human eye contrast sensitivity function and a perception contrast model, and calculating the image definition of a to-be-evaluated image; S2, selecting a target neighborhood and calculating the contrast based on the target neighborhood; S3, linearly combining the image definition with the contrast based on the target neighborhood, establishing a image sensing quality model and objectively evaluating the quality of the image. According to the invention, the image sensing quality model of the infrared polarization image is good in consistency with the subjective feeling of human eyes based on the visual characteristics of human eyes. In this way, the quality of the infrared polarization image can be objectively evaluated.

Description

technical field [0001] The present invention relates to the technical field of image processing, and more specifically, to an objective evaluation method and system for infrared polarization images. Background technique [0002] Polarization is one of the important characteristics of electromagnetic radiation. Since object reflection and self-radiation often have the polarization characteristics of the object itself, these differences in the target scene can provide new information for target detection. With the development of infrared focal plane detector technology, the sensitivity of the detector has been significantly improved, making infrared polarization imaging technology rapidly practical, and significantly improving the effectiveness of target detection in complex backgrounds or strong radiation interference backgrounds. [0003] Any target on the ground and in the atmosphere will produce polarization characteristics determined by their own properties and the basic ...
