1. DarkGray - 深灰色 RGB值: 169, 169, 169 Each color channel represents the intensity of red, green, and blue light, ranging from 0 (off) to 255 (full intensity). When all three color channels have the same value, the result is a gray shade with that particular level of...
value of RGB var_Max = max( var_R, var_G, var_B ) //Max. value of RGB del_Max = var_Max - var_Min //Delta RGB value L = ( var_Max + var_Min ) / 2 if ( del_Max == 0 ) //This is a gray, no chroma... { H = 0 //HSL results from 0 to 1 S = 0 } else...
1、HSV是一种将RGB色彩空间中的点在倒圆锥体中的表示方法。HSV即色相(Hue)、饱和度(Saturation)、明度(Value),又称HSB(B即Brightness)。色相是色彩的基本属性,就是平常说的颜色的名称,如红色、黄色等。饱和度(S)是指色彩的纯度,越高色彩越纯,低则逐渐变灰,取0-100%的数值。明度(V),取0-max(计算机中HSV...
RGB就是指Red,Green和Blue,一副图像由这三个channel(通道)构成; Gray就是只有灰度值一个channel; 2楼2022-07-03 18:44 回复 卡_卡 HSV即Hue(色调),Saturation(饱和度)和Value(亮度)三个channel。 HSV模型中颜色的参数分别是:色调(H:hue),饱和度(S:saturation),亮度(V:value)。由A. R. Smith在1978...

明度(我们的HSV中的V代表了Value) 颜色等效光谱各色相心理强度之和。可以从图中看到改变一个颜色的亮度,很可能会牵连到颜色光谱分布集中程度也就是饱和度,实际上不同的色彩体系对饱和度和明度的拆分是不同的。 色调看起来是最容易理解的概念,但事实上明度或者说亮度是最混乱的概念了:Brightness、Lightness、Value、...
Grayscale colormap, returned as a c-by-3 numeric matrix with values in the range [0, 1]. The three columns of newmap are identical, so that each row specifies a single intensity value. If you have Parallel Computing Toolbox installed, then newmap can also be a gpuArray object. Data...
Value IMREAD_UNCHANGED If set, return the loaded image as is (with alpha channel, otherwise it gets cropped). IMREAD_GRAYSCALE If set, always convert image to the single channel grayscale image. IMREAD_COLOR If set, always convert image to the 3 channel BGR color image. ...
