Automatic Design of High-Sensitivity Color Filter Arrays with Panchromatic Pixels

We propose a fully automatic approach to designing high-sensitivity CFAs using panchromatic pixels based on a mathematical model.

Optimized Color Filter Arrays for Sparse Representation Based Demosaicking

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

A Geometric Method for Optimal Design of Color Filter Arrays

We present a CFA design methodology in the frequency domain. The frequency structure, which is shown to be just the symbolic DFT of the CFA pattern (one period of the CFA), is introduced to represent im- ages sampled with any rectangular CFAs in the frequency domain.
