Image Quality Impact and Comparison of Selected State-of-the-Art CFA Interpolation Techniques

Among recent m ultimedia i maging s ystems single chi p cameras ar e do minating over t hree chip cameras. The si ngle chip cameras wi th a CF A as a color splitt ing system provide the R G B im ages with m utually d ifferent an d in complete sampling. The calculation of f ull resolut ion R G B im ages brings some problems and selected interpolation technique can affect the f inal image qual ity v ery s ignificantly. This pape r summarizes experimental results and performance comparison for four recent CF A in terpolation techniques. Having th e reference with re constructed im ages ava ilable, th e performance of each technique has bee n evaluated by objective criteria both PSNR and SSIM.
