De-Bayering (demosaicking) with NEON CoProcessor
Most of CMOS color chips provide the image in the bayer mosaicing (bayer raw) format. For get a color image in RGB format is it necessary to convert the bayer raw
image.

There are exist different algorithm for converting.

If the microprocessor does not include debayering hardware, have to do the converting via software. For this you need additional processing power and the
framerate goes down. It is better to use the NEON coprocessor of the i.MX6. For this support PHYTEC a special function.
It is present as GStreamer plugin "bayer2rgbneon" and in sources for use in an own C-program. We support a simple bilinear algorithm.
For use in GStreamer take "bayer2rgbneon" plugin. For more information to " bayer2rgbneon" parameters type:
