   - The camera provides video in RAW format, therefore [[http://​en.wikipedia.org/​wiki/​Bayer_filter|debayering]] is needed. This can be done for example by using the following commands. We could not figure out how to change the white balance for blue channel in the MATLAB environment,​ therefore blue channel must be multiplied by an appropriate value <​code>​im_debay(:,:,​1) = im(2:​2:​end,​1:​2:​end);​   - The camera provides video in RAW format, therefore [[http://​en.wikipedia.org/​wiki/​Bayer_filter|debayering]] is needed.
