而复杂的情况即不均匀采样时得到的结果会有偏差,这是很普遍的问题,采样越密的地方对误差校准贡献越大。在非均匀时权值自然是O^k/t(h),为了优化这个问题我们在半球上计算这个值时会让权值1/t(h)由此处h在Voronoi图(冯洛诺伊图/泰森多边形https://ww2.mathworks.cn/help/matlab/ref/voronoi.html)上的对应面积...

Photometric correction is a necessary step in planetary image pre-processing since the images of planetary surfaces are acquired by orbiting spacecraft at
Photometric stereo is used to estimate surface normal vectors in the non-occluded portions of the iris region. The variability of the normal vectors is used as the presentation attack detection score. This score is larger for a texture that is irregularly opaque and printed on a convex contact ...
The best results are provided by using our RANSAC-based variant of classical photometric stereo. The second part directly computes surface height from the images and the observation selections made in step 1. If you want to use all observations (for example if your object is approximately ...
