Function Documentation

void MalvarDemosaic	(	float *	Output,
		const float *	Input,
		int	Width,
		int	Height,
		int	RedX,
		int	RedY
	)

Demosaicing using the 5x5 linear method of Malvar et al.

Parameters:

Output	pointer to memory to store the demosaiced image
Input	the input image as a flattened 2D array
Width,Height	the image dimensions
RedX,RedY	the coordinates of the upper-rightmost red pixel

Malvar, He, and Cutler considered the design of a high quality linear demosaicing method using 5x5 filters. The method is essentially the bilinear demosaicing method that is "gradient-corrected" by adding the Laplacian from another channel. This enables the method to take advantage of correlation among the RGB channels.

The Input image is a 2D float array of the input RGB values of size Width*Height in row-major order. RedX, RedY are the coordinates of the upper-rightmost red pixel to specify the CFA pattern.
