Patent attributes
Dynamic warp map generation system and corresponding method are disclosed. A compactor obtains spatial transformation parameters along with geometric and optical distortion parameters and combines them to form hybrid grid data in a hybrid vector space. This vector space is divided into hybrid blocks. In each hybrid block, the grid dataset is fitted with a hypersurface and the surface coefficients are saved in an interface. A decompactor obtains dynamic control parameters representing varying distortion parameters and generates a hybrid space vector. According to the hybrid space vector, a warp map is decoded from the hypersurface coefficients that compensates for dynamic geometric and optical distortions. In another example of the present invention, the dynamic warp map generation system is used for color gamut transformation.
