Rui Wang · Jisuanji gongcheng · 2010
Aimed to identify the Color Filter Array(CFA) and interpolation algorithm in cameras,a joint identification method is presented.The approximately model of interpolation is established,under this model,the iterative error and Wiener solution from incremental Wiener filtering is exploited for joint estimation of color filtering pattern and interpolation coefficients,which is identified depending on the estimated interpolation coefficients.The performance of proposed method is analyzed from the statistical data.Experimental results show the efficiency of this method.
