自适应背景对消方法

Adaptive Background Cancel Method

本文讨论了一种新的红外图象预处理算法—自适应背景对消算法。这种算法的基本出发点是自适应L滤波具有很好的消除脉冲噪声的特性，红外图象中的点目标具有脉冲噪声的特性和红外噪声的相关特性。实验表明这种算法在某种程度上去除了原始图象噪声的相关性并且能明显的抑制背景噪声和显著提高信杂比。

A new preprocessing algorithm for infrared image, adaptive background cancel algorithm, is developed in this paper. This algorithm is based on the adaptive L-filter's characteristic of filtering impulse noise well.The noise of dim target in the infrared image has the characteristic of impulse noise and infrared noise. The experiment result show that this algorithm can surpress background noise well obviously raiae signal-clutter-ratio and can get rid of the relativity of original image noise.
