OpenCV中OpponentColorDescriptorExtractor_OpenCV

class  OpponentColorDescriptorExtractor

實現了在d對立色彩空間(Opponent Color Space)中計算特徵描述子的類. (Van de Sande et al., CGIV 2008 Color Descriptors for Object Category Recognition). Input RGB image is transformed in the Opponent Color Space. Then, an unadapted descriptor extractor (在建構函式中設定) 計算映像三個通道中的每個通道對應的特徵描述子和 串連它們成單一顏色特徵描述子.

class OpponentColorDescriptorExtractor : public DescriptorExtractor{public:    OpponentColorDescriptorExtractor( const Ptr<DescriptorExtractor>& dextractor );    virtual void read( const FileNode& );    virtual void write( FileStorage& ) const;    virtual int descriptorSize() const;    virtual int descriptorType() const;protected:    ...};
