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.

RGB, HSI, YUV and YCbCr color spaces, infrared image, image fusion, false color, color transfer algorithm, histogram, and bilinear interpolation.
