Demosaicing using subband‐based classifiers
Da‐Cheng Sung, Hen‐Wai Tsao · Electronics Letters · 2015
A new wavelet‐based interpolation algorithm to improve the performance of colour filter array (CFA) interpolation is exploited. The purpose of a CFA is to filter a single colour in digital still camera images. A CFA interpolation can then restore full colour to images captured by the CFA. The proposed classifier can effectively restore edge information and reduce the complexity of computation.
