摘　　要：彩色图象虽然比灰度图象多了一个色彩信息 ,但在彩色图象的获得过程中往往容易受到环境光线的干扰 ,这对彩色图象的处理和分析带来很大的困难 .本文利用二色反射模型对几种彩色模型的光照稳定性进行了分析 ,然后用颜色试验进行了验证 .结果表明 ,rgb和 HS在白光下具有光强不变性 ,m1m2 m3在不同强度和颜色的光照下都表现了较高的稳定性 .经改进后的 m1m 2 m 3(n1n2 n3)减弱了噪点的影响 ,稳定性更好 .Color images give more information than gray images. However, when captured by the camera, they are easily disturbed by the illumination circumstance. It brings the difficulties to the processing and analyzing of color images . In this paper, we have discussed the stability of some color models (RGB, HIS, rgb, La*b*, m1m2m3 and YUV) to illumination using the dichromatic reflection theory, then validated it with the color experiments. The results make clear that the rgb and HS are invariant to white illumination in different intensity and the m1m2m3 exhibition the stability to lights both in different intensity and different color . The new model (n1n2n3) Improved on the m1m2m3 shows better characteristic after eliminating the effect of the noise.
