代码描述

中文说明:使用三个不同暴露单幅图像的恢复在阴影和高光细节生成的图像。曝光不足的区域基于像素强度与输入的图像进行分析,找到了。输入图像的局部对比度也被认为是以生成输出图像正确的颜色以不同的方式公开的区域之间的交易。然后图像合并使用的混合功能。拟议的方法要求单通过图像来生成结果,使得处理一个图像小于 100 毫秒。拟议的方法要求没有摄像机或关闭条件,快门速度和光圈大小等信息。


English Description:

Using three differently exposed images a single image with recovered details in shadows and highlights is generated. Input images are analyzed to locate over and underexposed regions based on pixels intensity. Local contrast of input images is also considered in order to generate the output image with correct color transactions between differently exposed areas. Then images are merged using blending function. The proposed method requires a single pass thru the image to generate the result, which allows to process one image for less than 100 milliseconds. The proposed method requires no information about camera or shutting conditions, such as shutter speed or aperture size.
