Firstly, it turns the original image into CIELAB color space, then computes histograms of L and a separately.

该方法首先将原始图像变换到CIELAB颜色空间，然后对所得图像的L和a分量分别进行直方图统计。

A whiteness formula in the CIELAB uniform color space is developed in this paper. Several whiteness formulas are analyzed and compared.

本文提出了在CIELAB匀色空间中的白度公式，并与其它白度公式进行了分析和比较。

Detailed analysis of the corresponding color vision characteristics implies that the CIELAB space is also not visually uniform for suprathreshold color differences.

基于相应颜色视觉辨别特性的分析说明，CIELAB颜色空间对于阈上色差也是非视觉均匀的。
