Dealing with faces illumination variation based on dynamic directional gradient vector flow snake and gamma algorithm a new dynamic directional gradient vector flow snake ddgvf snake algorithm was presented which can detect the image shadow and highlight contours of the unknown face images. according to the given standard face database, the image gray median could be c.
使用一種動態方向梯度矢量流snake ddgvf snake演算法來檢測未知圖像的陰影和高光區域，根據已知的標準人臉圖像庫中圖像的灰度分佈，計算出灰度中值，然後採用加權非線性gamma灰度矯正演算法來歸一化待識別圖像的光照變化，使之與已知的標準庫中的圖像灰度一致。 -
Presents a method for sfs based on model of polyhedron. we carry out the algorithm by solving a overdetermined linear equations which is constructed through the distributing of the vector field. the algorithm can reconstruct 3d surface from photometric stereo image given the direction of illumination
針對目前「從明暗恢復物體形狀方法」存在的問題，提出了以多面體模型為基礎的快速演算法，根據向量場的分佈建立關於物體表面深度信息的超定線性方程組，在最小二乘意義下求得物體表面的深度值。 -
