亮度信息 meaning in English

luminance information
monochrome information

The results show that 1 ) the linear transform colospaces have better performance than others , and 2 ) the absence of the luminance component decreases performance significantly
结果表明：线性颜色空间是最优的肤色空间类，去除亮度信息将降低肤色非肤色的类可分离性，并导致分类性能的退化。
Firstly , this dissertation studies on the detection algorithms of highlight and shadow of tongue images in the preprocess flow . an adaptive area / lightness - based highlight detection algorithm and an improved shadow detection algorithm eliminating marginal shadow are proposed . by comparing with other algorithms , we find that the experiment results of the proposed algorithms are better
首先,本文对预处理过程中反光点和阴影点的检测算法进行了研究,并提出了一种动态自适应的基于面积和亮度信息的反光点检测算法和一种能去除边缘阴影的阴影点检测算法,取得了良好的效果。
