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

We consider a simplified algorithm for fusion of greyscale visible and thermal images presented in false colors in the de-correlated YCbCr 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 1024×768 pixels and a frame rate of 30 Hz.
