High-Quality Gradient-Corrected Linear Interpolation for Demosaicing of Color Images

摘要

The gradient-corrected linear interpolation method and system for demosaicing (demosaicing) of a color image is provided. A method and system to calculate the term (such as the gradient of the desired colors of the given pixel) and calculates the interpolation, a correction using the predetermined state of the art (bilinear interpolation technique for satisfactory, reducing the computational complexity) and, in combination with a correction term as a linear interpolation, to produce a high quality correction of the color interpolation in the pixel value loss. Correction term can be calculated from the current anti-Japanese currently gradient correction of the pixel color. This gradient affects the color of the estimated values ​​generated by the conventional interpolation technique is directly used to correct the value. The gradient-corrected linear interpolation method and system may also apply a gradient to the gradient correction gain correction term. The gradient correction gain affects the gradient correction to be applied to the interpolation. ; Gradient compensation, linear interpolation, bilinear interpolation, the correction term, the support area, the correction gain
