摘要：

A novel method for obtaining local high-frequency components of the missing colour channel in weak correlated colour filter array (CFA) data, by calculating the local inter-channel high-frequency correlation coefficients, is proposed. The contrast of experimental results demonstrates that the high-frequency components achieved by the proposed method are closer to the original image than those from state-of-the-art approaches.
