红外目标图像识别技术已经广泛地应用于各个领域，基于小波变换的红外图像识别存在明显不足，主要表现在小波系数的振荡性、移变性、频谱混叠性以及二维小波变换缺乏方向性。轮廓波变换的提出和发展很好地解决了这些问题。设计开发了基于轮廓波变换的红外目标图像动态实时识别系统，很好地实现了红外目标图像的动态实时获取，且其应用前景广泛。
紅外目標圖像識彆技術已經廣汎地應用于各箇領域，基于小波變換的紅外圖像識彆存在明顯不足，主要錶現在小波繫數的振盪性、移變性、頻譜混疊性以及二維小波變換缺乏方嚮性。輪廓波變換的提齣和髮展很好地解決瞭這些問題。設計開髮瞭基于輪廓波變換的紅外目標圖像動態實時識彆繫統，很好地實現瞭紅外目標圖像的動態實時穫取，且其應用前景廣汎。

The recognition technology of infrared target image has been widely used in various fields,but the infrared image recognition based on wavelet transform has obviously insufficient,which is mainly reflected in oscillatory performance,migration performance and spectrum aliasing of the wavelet coefficient and lacking directivity in two?dimensional wavelet transform. With the development of the contourlet transform,the above problems were well solved. The dynamic and real?time recognition system of the infrared target image based on contourlet transform was designed and developed,which can better realize the dynamic and real?time acquisition of the infrared target image,and has wide application prospect.
