Abstract: An image having m light sources, with m preferably equaling 2 or 3, is segmented into different regions, each of which is lit by only one of the m light sources, by obtaining paired imaged with different filtering, for example a filtered and an unfiltered image, applying to the image pairs sets of m pre-computed mappings at the pixel or region level, and selecting the most appropriate. The rendering of the information in the image maybe adjusted accordingly.

Abstract translation: 具有m个光源的图像，其优选地等于2或3，被分割成不同的区域，每个区域仅通过m个光源中的一个被点亮，通过获得具有不同滤波的成对成像，例如滤波和未滤波 图像，应用于在像素或区域级别的m个预先计算的映射的图像对集合，并且选择最合适的。 图像中的信息的渲染可以相应地进行调整。
