Thermal infrared human body target recognition method based on monotonic wave direction energy histogram

Abstract

The invention discloses a thermal infrared human body target recognition method based on a monotonic wave direction energy histogram, which comprises the following steps: obtaining a thermal infraredimage containing a human body target; extracting a candidate human body target region from the thermal infrared image, wherein the candidate human body target region refers to an image region suspected to contain a human body target in the thermal infrared image; extracting characteristics of a monotone wave direction energy histogram of the candidate body target region; and based on the characteristics of the monotonic wave direction energy histogram, the candidate human body target region is classified and identified, and the candidate human body target region containing the human body target is determined to realize the recognition of the human body target in the thermal infrared image. The characteristics of the monotonic wave directional energy histogram can express the blurred edgesof the thermal infrared image under strong noise disturbance, so it has strong discrimination. By adoption of the characteristics of the monotonic wave direction energy histogram, the accuracy of human body target recognition can be effectively improved..

Description

technical field [0001] The invention relates to the technical field of digital image processing and pattern recognition, in particular to a thermal infrared human target recognition method based on a monotone wave direction energy histogram. Background technique [0002] Human target recognition technology is widely used in battlefield reconnaissance, intelligent transportation, security monitoring, intelligent robots and many other fields. In recent years, with the advancement of the technical level of thermal infrared imaging equipment and the continuous decline of prices, more and more researchers have carried out research on human target recognition technology under thermal infrared imaging conditions. Thermal infrared imaging equipment performs imaging by detecting the thermal radiation of objects in the environment, so it can work normally in the case of poor lighting or even no visible light. Therefore, the human target recognition application system using thermal inf...
