An issue of diagonal stripe patterned color filter array (CFA) is introduced in this paper. This is a procedure known as color interpolation, aka demosaicking. Both of objective and visual assessments are researched, and the simulation results are shown in the paper. It was found that our proposed filter yields good objective performance with excellent visual quality.

This paper addresses the problem of color restoration on Lukac color filter array (CFA) pattern [. Digital camera acquires the continuous color spectrum using three filters. However, each pixel indicates only a sample out of three channels. This order is called a mosaicking and the opposite process is called demosaicking. This article designs filters for Lukac CFA, and apply it to generate demosaicked images. The objective (CPSNR and S-CIELAB) and visual quality comparison are provided in simulation results section.

This paper introduced a problem of the modified Bayer pattern color filter array (CFA). A demosaicking method is also known as color interpolation, which is a digital camera process employed to restore a full-color imagery from an image with missing color information. In general, a CFA pair contains two green pixels and one red and blue pixel (RGGB). However, there exist alternatives such as RRGB or RGBB. In this paper, we study the effect of three different color arrays. Simulation results show that the obtained filters give good performance.
