17-8 冗長Haar Wavelet変換を用いた線形デモザイキング法(第17部門 画像処理)

抄録

The color-imaging scheme with the 4-color CFA has the advantage of restoring high spatial-frequency components very successfully, but it has the disadvantage of poor color reproduction. To improve the color reproduction of the color-imaging scheme with the 4-color CFA, this paper proposes a new linear demosaicing method with the undecimated Haar wavelet transform, and demonstrates its superiority in color reproduction over the existing linear demosaicing methods.
