中值等值線圖-
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。
