Abstract
Techniques for demosaicing of digital color images are improved by estimating and using the structural instability in the neighborhood of the respective pixel. The structural instability for a color is given by the range of the color values for this color in a first local region around each current pixel. A method is executed by a device for interpolating a missing color at the current pixel in a color image produced by a digital image sensor having a color filter array, the current pixel having a current color that differs from the missing color. The method comprises: computing () a range value for one of: pixels having the missing color and pixels having the current color; computing () an interpolation value at the current pixel as a function of the range value and color values for pixels having the missing color within a second local region around the current pixel; and setting the missing color at the current pixel to the interpolation value.
