Partition-based interpolation for color filter array demosaicking and super-resolution reconstruction
Min Shao, Kenneth E. Barner, Russell C. Hardie · Optical Engineering · 2005
A class of partition-based interpolators that addresses a vari- ety of image interpolation applications are proposed. The proposed in- terpolators first partition an image into a finite set of partitions that cap- ture local image structures. Missing high resolution pixels are then obtained through linear operations on neighboring pixels that exploit the captured image structure. By exploiting the local image structure, the proposed algorithm produces excellent performance on both edge and uniform regions. The presented results demonstrate that partition-based interpolation yields results superior to traditional and advanced algo- rithms in the applications of color filter array CFA demosaicking and super-resolution reconstruction. © 2005 Society of Photo-Optical Instrumentation
