Demosaicing of Color Images Using Steerable Wavelets
Yacov Hel-Or, Daniel Keren · 2002
In some types of digital color cameras only a single value is provided for each pixel: either, red, green, or blue. The reconstruction of the three color values for each pixel is known as the "demosaicing" problem. This report suggests a solution to this problem based on the steerable wavelet decomposition. The reconstructed images present a faithful interpolation of missing data while preserving edges and textures.
