  This paper developed a brightness enhancement technique for video frame pixel
intensity improvement. Frames extracted from the six sample video data used in
this work were stored in the form of images in a buffer. Noise was added to the
extracted image frames to vary the intensity of their pixels so that the pixel
values of the noisy images differ from their true values in order to determine
the efficiency of the developed technique. Simulation results showed that, the
developed technique was efficient with an improved pixel intensity and
histogram distribution. The Peak to Signal Noise Ratio evaluation showed that
the efficiency of the developed technique for both grayscale and coloured video
frames were improved by PSNR of 12.45%, 16.32%, 27.57% and 19.83% over the grey
level colour (black and white) for the NAELS1.avi, NAELS2.avi, NTA1.avi and
NTA2.avi respectively. Also, a percentage improvement of 28.93% and 31.68% were
obtained for the coloured image over the grey level image for Akiyo.avi and
Forman.avi benchmark video frame, respectively.
