Recent studies have shown that panchromatic colour filter arrays possess better light intensity properties than the more prevalent Bayer array. This is an attractive property in integrated camera design. Demosaicking algorithms, however, focus primarily on Bayer-based cameras because of their simple demosaicking process. This paper presents a novel algorithm for use in the RGBW class of panchromatic...
Demosaicking is a digital image process to reconstruct full color digital images from incomplete color samples from an image sensor. It is an unavoidable process for many devices incorporating camera sensor (e.g., mobile phones, tablet, and so on). In this paper, we introduce a new demosaicking algorithm based on polynomial interpolation-based demosaicking. Our method makes three contributions: calculation...
Conventional Fourier transform profilometry (FTP) suffers from spectrum overlapping arising from ambient light, surface reflectivity and system nonlinearity. In this paper, we propose a binary coding strategy to address the problem. First, we decompose a grayscale FTP pattern into a serial of binary patterns; second, we project the binary patterns onto a target and image the corresponding patterned...
