Web24 de jan. de 2024 · 使用python编写了共六种图像增强算法: 1)基于直方图均衡化 2)基于拉普拉斯算子 3)基于对数变换 4)基于伽马变换 5)限制对比度自适应直方图均衡化:CLAHE 6)retinex-SSR 7)retinex-MSR其中,6和7属于同一种下的变化。 将每种方法编写成一个函数,封装,可以直接在主函数中调用。 采用同一幅图进行效果对比。 图像增强的效果为: … WebRetinex算法所做的就是合理地估计图像中各个位置的噪声,并除去它。 在极端情况下,我们大可以认为整幅图像中的分量都是均匀的,那么最简单的估计照度L的方式就是在将图像变换到对数域后对整幅图像求均值。
