Eyes Location Based on the Calculation of the Complexity Extent and the Best Threshold Value
Gu Shusheng · Control Engineering of China · 2008
The eyes location problem in intelligence of human face detection is studied.A new algorithm that can detect directly and orient the human eyes in human face images with background gradation is proposed,and it does not need to determine the human face position firstly.The method uses the conception of the complexity extent to carry on the fast orientation for the eyes position in human face images,and it cuts the image blocks near eyes.Then it uses image division principle to seek the best threshold value automatically and withdraws the edges of the eyes.It finally carries on the morphology operation to remove the image blocks of the human eyes,thus orienting the position of the eyes correctly.Massive simulation and experiments show that the proposed method is effective in raising the speed of eyes location,and can be applied to real-time situation.
