Abstract
By analyzing the conversion algorithm between RGB and HSV, this paper proposes a fast algorithm to convert RGB space to HSV space. The algorithm adopts shift operation and lookup table instead of floating-point multiplication, which greatly improves the speed of the algorithm on FPGA. In addition, the Y component is no longer involved in the calculation during the conversion, which further reduces the computational complexity. Finally, experiments show that compared with the traditional algorithm, the algorithm can save 80% of the computing time on the FPGA platform and 46% on the PC platform. Therefore, this algorithm is widely used in real-time video analysis such as license plate recognition and flame detection.
