本文提出了基于Retinex可变框架模型的图像增强算法。实验证明该算法不但能有效的增强图像的质量,还能避免Retinex算法中带来的光晕效应,同时算法速度与同类型的图像增强算法比较更快速。之后,将这种理论运用到对彩色图像增强中,取得了很好的处理效果。

图像二值化是建立在物体和背景可以区分的基础上的,如亮度色调等不同,从而我们根据这些已知信息分出前背景。而一般的全局二值化如用Otsu方法获取最优阈值的方法,都是建立在图像前背景亮度有一定差距的基础上的,即图像直方图有双峰结构。
如果对于一幅亮度不均匀的图像这种方法就不适用,解决的方法可以把图像根据整体亮度变化来分成若干小区域,而各区域的直方图中有两个峰,这样就能自适应得时整幅图都比较好的二值化。但是,这样对于一些复杂的图像就难处理,而且可能存在分块邻接缺陷,因此,本程序中先将整幅图的亮

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
