Abstract

After a brief review of the possibilities of implementing an algorithm, we analyze the implementation of an algorithm for coloring a monochrome image in an FPGA (Field Programmable Gate Array) circuit. Each pixel in shades of gray in the monochrome image receives one of 16 possible colors, according to its position in the color image. Although the approximation is crude, given that the original image has more than 16 million distinct colors, a comparison between the two images indicates a PSNR (Peak Signal to Noise Ratio) value of almost 25 dB, and the appearance of the color image is acceptable. The algorithm was implemented in the MATLAB environment and then in the FPGA using the integrated Xilinx ISE design environment. The color images generated in this way were identical, but the execution speed in FPGA was 185 times faster.
