Implementation of an algorithm for forming a color image from monochrome images of visible and near infrared cameras in the $YC_bC_r$ color space

We consider a simplified algorithm for fusion of greyscale visible and thermal images presented in false colors in the de-correlated $YC_bC_r$ color space. The color gamut is then brought to daylight conditions using a color transfer algorithm that provides the same luminosity of the resulting gray fusion and color fusion images. It is shown that the parallel computing on the graphics card performs real-time video fusion with a frame size of up to $1024\times768$ pixels and a frame rate of 30 Hz.
