我们提出了一种方法，用于分离纹理表面上的高光反射。与使用来自高亮区域外部的漫射颜色信息来约束解决方案的先前技术相比，所提出的方法进一步利用颜色的空间分布来解决分离中经常出现在真实的图像中的模糊性。对于高光像素，其中一个明确的分离不能从颜色空间分析确定，我们评估可能的分离解决方案的基础上，他们的一致性与漫射纹理特征以外的高光。考虑到颜色空间和图像空间中的颜色分布，在具有挑战性的情况下可以获得明显增强的分离性能。
We present a method for separating highlight reflections on textured surfaces. In contrast to previous techniques that use diffuse color information from outside the highlight area to constrain the solution, the proposed method further capitalizes on the spatial distributions of colors to resolve ambiguities in separation that often arise in real images. For highlight pixels in which a clear-cut separation cannot be determined from color space analysis, we evaluate possible separation solutions based on their consistency with diffuse texture characteristics outside the highlight. With consideration of color distributions in both the color space and the image space, appreciably enhanced separation performance can be attained in challenging cases.
