The paper deals with a new interpolation technique for reconstruction of nonuniformly and irregularly sampled color images. The assumption is that there is at least one densely sampled component known (the luminance component). The presented technique is a simple noniterative adaptive approach that exploits intercomponent correlation of natural scene images. The approach is based on adaptive adjustment of triangle interpolation coefficients. A simple adaptation rule is derived from analysis of gradient magnitudes that exhibit high correlation between color components in natural scene images. This scenario is employed in very low bit rate coding of color images with nonuniform sampling applied to chrominance components.
