Implements 3 types of interpolation: bicubic, bilinear and nearest-neighbor on black-and-white and ... WebOne basic demosaicking method is bilinear interpolation, which fills missing color values with weighted averages of their neighboring pixel values. Although this method is simple, it introduces severe demosaicking artifacts and smears sharp color edges. For better performance, more sophisticated CFA demosaicking methods [2]-[7],[9],[11] have been
