- 在人和机器统一的颜色空间基础上,颜色恒常性用于描述对象在光照及环境变化时的一种性质。相对人类视觉而言,是指视觉系统在光照及环境变化时对物理表面的稳定的知觉,是一种认知现象。相对于机器视觉而言,是机器视觉系统关于物理表面光谱反射率的描述[2]。常见的RGB颜色空间上每一个象素的R、G、B值-machines and the reunification of the color space based on Color Constancy used to describe objects and t

- Retinex理论的基础理论是物体的颜色是由物体对长波(红色)、中波(绿色)、短波(蓝色)光线的反射能力来决定的,而不是由反射光强度的绝对值来决定的,物体的色彩不受光照非均匀性的影响,具有一致性,即retinex是以色感一致性(颜色恒常性)为基础的。不同于传统的线性、非线性的只能增强图像某一类特征的方法,Retinex可以在动态范围压缩、边缘增强和颜色恒常三个方面打到平衡,因此可以对各种不同类型的图像进行自适应的增强。-The basic theory of Retinex theory is

- 在一般的拍摄情况下,光照是平行均匀地照射到物体上的,往往关注光源颜色的变化而忽略了亮度信息,导致校正效果不理想,于是提出了基于亮度的改进算法。该算法的基本思想是,将图像均匀分块求取中心像素并对亮度进行加权,然后求取近似于整幅图像R、G、B三分量的平均灰度值,改进GrayWorld算法时用亮度加权取代了平均灰度值,最后将它与White-patch算法整合到一起,建立方程组解出调节参数,并根据参数进行调整。-In normal shooting situations, the light is un
