Function:DemosaicDFPD

Restores an RGB image from a CFA image using DFPD Bayer algorithm. Directional Filtering with Posteriori Decision to restore the color image gives much better results than demosaic (with bilinear interpolation) and remove artifacts.

Function

CuviStatus demosaicDFPD(const CuviImage& src, CuviImage& dst, const CuviBayerSeq sensorAlignment, bool refineResults, const CuviStream& stream = CuviStream());

Parameters

Name Type Description src const CuviImage& Input Bayer Image dst CuviImage& Output RGB Image sensorAlignment CuviBayerSeq Sensor alignment of the bayer image refineResults bool Perform additional refinement step stream const CuviStream& GPU stream ID for execution

Image Type Support

Input Output 8u 8u 16u 16u
