Select here the demosaicing RAW images decoding interpolation method.

Also " +"known as CFA interpolation or color reconstruction, another common spelling is " +"demosaicing. There are 4 methods to demosaicing RAW images:" +"

Bilinear: use high-speed but low-quality bilinear interpolation " +"(default - for slow computer). In this method, the red value of a non-red pixel " +"is computed as the average of the adjacent red pixels, and similar for blue and " +"green." +"

VNG: use Variable Number of Gradients interpolation. This method " +"computes gradients near the pixel of interest and uses the lower gradients " +"(representing smoother and more similar parts of the image) to make an " +"estimate." +"

PPG: use Patterned Pixel Grouping interpolation. Pixel Grouping uses " +"assumptions about natural scenery in making estimates. It has fewer color " +"artifacts on natural images than the Variable Number of Gradients method." +"

AHD: use Adaptive Homogeneity-Directed interpolation. This method " +"selects the direction of interpolation so as to maximize a homogeneity metric, " +"thus typically minimizing color artifacts." +"
