Infrared radiation and bicolor ratio are studied in the paper.The gray and space feature of infrared quasi imaging is analyzed. 研究了紅外雙色輻射特性和雙色比識別特征，分析了紅外亞成像的灰度與空域特征。
The separability of multiple targets is increased by maximizing the mutual information between the characteristics of the target and the feature extracted. 該方法通過(guò)最大化識別特征與目標特性之間的互信息以達到增加各類(lèi)目標可分性的目的。
