The primary subject of this paper is to (1) The negative-selection algorithm that can be detected abnormity is improved by the mutation mechanism of genetic algorithm.

本文所做的主要工作如下(1)借助遗传算法中变异的机制，对能检测出异常变化的阴性选择算法作了新改进。

Thus, a method of weak and small target detection in infrared image sequences is proposed based on the least absolute deviation background prediction and the genetic algorithm.

因此提出了基于最小一乘估计和遗传算法进行背景预测的红外弱小目标检测方法。

The key to feature extraction is to select the optimal feature combination from all the features. In this study, the optimal color feature combination,{/G,(R+4G+B)/6, H variance, S variance}, is selected using genetic neural network at first. Then the main texture features including the mean, variance, energy and entropy of the cooccurrence matrix, the secondary texture features including the maximum frequency number, absolute uniform, inertia and importance of the co-occurrence matrix are extracted.

在此基础上，提出适合多阈值和小目标图像分割的免疫遗传图像分割方法，该方法借鉴了生物免疫系统自调节、抗原识别和记忆功能，并结合了遗传算法对图像进行自适应区域的阈值分割，改善了遗传算法优化复杂问题时存在收敛速度慢和易陷于局部最优的不足，克服了传统阈值分割方法对目标大小的限制，是一种新型的有效的图像分割方法。
