在一个rgb值中，任何给定的通道都可以包含一个从0(无色)到255(完整颜色)的值。
In an RGB value, any given channel can contain a value anywhere from 0 (no color) to 255 (full color).
一个拥有不透明通道的子类需要重写这个方法来返回指定了透明值的颜色对象。
A subclass with explicit opacity components should override this method to return a color with the specified alpha.
初始化并返回颜色对象使用不透明的HSB颜色空间通道值。
Initializes and returns a color object using the specified opacity and HSB color space component values.
请注意，当引用灰阶图像文件，关于编码灰阶值的线性光值的转换曲线，必须考虑到计算时的颜色通道。
Note that when referencing a grayscale image file, the transfer curve relating the encoded grayscale values to linear light values must be taken into account when computing the color channels.
其次，对图像进行多通道融合的颜色分割并对分割后的图像进行二值化处理，并分割可能粘连的交通标志。
Secondly, the color segmentation of image using multi-channel and the binarization of image is implemented and the traffic signs which may be adhered are divided.
