Query: Lossless White Balance For Improved Lossless CFA Image and Video
  Compression   Color filter array is spatial multiplexing of pixel-sized filters placed over
pixel detectors in camera sensors. The state-of-the-art lossless coding
techniques of raw sensor data captured by such sensors leverage spatial or
cross-color correlation using lifting schemes. In this paper, we propose a
lifting-based lossless white balance algorithm. When applied to the raw sensor
data, the spatial bandwidth of the implied chrominance signals decreases. We
propose to use this white balance as a pre-processing step to lossless CFA
subsampled image/video compression, improving the overall coding efficiency of
the raw sensor data.
