Conversion of Color Space Between YUV and RGB on SSE2 Technique
The conversion should be completed from the YUV color space to RGB color space in video processing. In this paper
by analyzing the YUV format and RGB format conversion algorithm
floating point operations is replaced by integer operations and divisible by 256 corresponds to eight right shift operation to increase the speed of calculation. Combine intel single instruction
multiple data extension SSE2 instruction set technology optimization algorithm
the efficiency of the different digital video format conversion is significantly improved. Experiments prove that SSE2 technology can increase by 25 times the computational speed and has a good application in the video processing.
