Color demosaicking is a significant step that enables digital cameras to recover full pixels from a raw image. In this paper, we propose an efficient color image demosaicking model based on guided upsampling. Guided upsampling using residual interpolation has been prominent in comparison to other methods. In the present study, we developed an adaptive guided upsampling method without RI. Our approach consists of adaptive guided upsampling and color-component difference interpolation. We utilize color difference interpolation and guided upsampling for its preprocessing in the G channel interpolation and interpolate the R and B channel with guided upsampling using recovered G channel. The results of the experiments prove that our approach is superior to RI-based methods on both objective and subjective performance for the Kodak and the IMAX datasets.
