Real-time implementation of an LUT-based image warping system

Image warping is a spatial transformation distorting an original image, and an elementary operation of image warping is moving pixel data to another position. Millions of iterations of the simple operation is adequate to be implemented using digital hardware better than software running on a CPU, and parallel architecture enables real-time processing. In this paper, a hardware architecture for real-time image warping using look-up table(LUT) is presented. An overall hardware architecture including buffer memories is explained. Finally, the hardware architecture is implemented using FPGA, and experimental results are presented.
