Applying visibility to evaluate and analyze thermal images under obscured IR smoke screen conditions

摘要

Abstract: The paper emphatically inquires into effective methodthat describes effects of smoke screen on thermalimage. In order to accurately reflect and describe theimpact of IR smoke screen on thermal image as far aspossible, regarded as a kind of audio-visual scheme,visibility judgement of target is adopted. That is,statistical mean of discernible area of target inproportion to overall area of target is judged in thecourse of releasing smoke screen. Moreover, the dataobtained is processed further and one kind ofcomprehensive evaluating method is given. !2
