It is necessary to adopt a hierarchical approach to land allocation to satisfy the most immediate and productive use 政府有必要建立土地分配的優先次序,以滿足最迫切需要及達致最大的土地使用成效。
In this paper , we present a multi - feature optimal fusion algorithm , inclusive of skin color , to detect one or multiple faces in color image with complex background . it is a hierarchical approach and integrates the skin color segmentation , face template matching and a neural network frontal face detector . with the elimination of false areas , the search area will become smaller and smaller , and the detection will be accomplished eventually 該算法是一種層次式、由粗到精的檢測方法,按照“分割-搜索”的檢測模式,將膚色分割、平均臉模板匹配與神經網絡驗證結合起來,采取逐步排除的方法,一步一步縮小搜索區域,實現彩色圖像中單個或多個正面端正人臉的檢測與定位。
