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
