Optimized Color Filter Arrays for Sparse Representation Based Demosaicking. TIP, 2017.

In this paper, we consider optimally designing CFAs for sparse representation-based demosaicking, where the dictionary is well-chosen.
PDF

Penrose High Dynamic Range Imaging. JEI, 2017.

We propose the Penrose pixel layout, using pixels in aperiodic rhombus Penrose tiling, for HDR imaging.
