HSV色彩空间(Hue-色调、Saturation-饱和度、Value-值)将亮度从色彩中分解出来,在图像增强算法中用途很广。在图像处理项目中,经常将图像从RGB色彩空间转换到了HSV色彩空间,以便更好地感知图像颜色,利用HSV分量从图像中提取感兴趣的区域。 HSV色彩空间也被称为HSB(色调、饱和度、亮度),在PS中常被用到。 HSV色彩空间...
CSS颜色有三种表示方式 颜色名称,如”red”、”green”、”blue”等 RGB值,如“rgb(255,0,0)” #符号后接4位的十六进制数值,如“#ff0000” CSS中使用颜色名称指定颜色 CSS中使用RGB值指定颜色 CSS中使用十六进制值指定颜色 RGB颜色查询对照表
3. HSV模式 HSV模式也称为HSB模式,由色相(Hue)、饱和度(Saturation)和明度(Value)三个参数组成。这种模式将色彩信息和明暗信息分开,更符合人眼对颜色的感知。HSV模式适合进行颜色调整、筛选等操作,但在实际应用中较为少见。二、如何选择合适的色彩模式 在摄影中,选择合适的色彩模式是提升作品质感的关键。那么...
