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。

Rat in Group B was set an air bladder which was empty and not perfused water. Water of 0.6 ml, 0.8 ml, 1.0 ml, 1.2 ml, 1.4 ml and 1.5 ml was perfused respectively into the air bladders which were set in the colon of rats in group C, D, E, F, G and H. Then the changes of ethology of the rats were recorded in interval of an hour.

During the period of AFB1-treatment, group A and B were fed with the food containing 9.3 and 2.3 g/kg of Jin-pu respectively, while Group C was fed with normal food only. Eight weeks later, the autoptic liver tissues from each animal were checked for number and size of γ-glutamyltranspeptidase-positive hyperplastic liver cell foci. RESULTS: Number and size of AFB1-induced γ-GT foci by both high and low dosages of Jin-pu were inhibited.

For the evaluation of cathode-ray tubeperceptible color difference threshold characteristics of the visual color matching, the experiment is carried out. By using the compiled color-matching program, the CRT generates color under gray background randomly.

为了对阴极射线管(Cathode ray tube，CRT)显示器颜色恰可辨别的小色差阈值进行评价，在中性灰背景下，用编制的颜色匹配程序，在CRT显示器上随机产生颜色，分别调节程序中R、G、B通道的值，使匹配色与随机色达到视觉上的一致，进行颜色视觉匹配实验，测量CRT显示器上随机色和匹配色的L*a*b*值。
