內容摘要：
This seminar addresses the problem of interpolating missing color components at the output of a Bayer color filter array (CFA), a process known as demosaicking. A luma-chroma demultiplexing algorithm is presented in detail, using a least-squares design methodology for the required bandpass filters. A systematic study of objective demosaicking performance and system complexity is carried out, and several system configurations are recommended. The method is compared with other benchmark algorithms in terms of CPSNR and S-CIELAB ΔE * objective quality measures and demosaicking speed. Finally, some deep learning-based image processing applications are introduced. In addition, various application results based on artificial intelligence are introduced through examples.
