红外图像复杂度评估方法综述

摘要

Infrared image complexity is an important index in the evaluation of infrared guided weap-on.Within the tremendous complicated combat environment , automatic target recognition ( ATR) faces big challenges.Therefore, accurate and objective evaluation of image complexity has great value for ATR’ s improvement .In this paper, image complexity ’ s concept is firstly discussed, and then current e -valuation methods of the complexity are overviewed .Finally , useful evaluation indexes are introduced for ATR application.%红外图像复杂度是评估红外成像制导武器作战性能的重要指标，由于现实作战对抗环境的复杂多变，红外目标自动识别（ ATR）面临巨大挑战，因此准确客观地评价红外图像复杂度对考核提升自动识别技术具有重大现实意义。针对红外目标自动识别的应用背景，深入探讨了红外图像复杂度的内涵，对现有红外图像复杂度的评估方法进行综述分析，并介绍了面向ATR应用的复杂度描述指标。
