A Look-Up-Table based skin color segmentation method

A novel and real time FPGA skin color segmentation method is presented in this paper. Since most of the traditional skin segmentation methods have the problems of relatively large delay and complexity, they are not fit for real-time applications. To settle this problem, this paper proposes to use the Look-Up-Table (LUT) method for skin segmentation which has very fast operation speed. The method is implemented on an FPGA device modeled by Verilog HDL and targeted for Altera DE2-70 board. 17 ALUTs and 1024 bits of memory are used, when the FPGA system is running at a pixel rate of 27MHz. This skin color segmentation method can be used in many kinds of non-touch and real-time human computer interactive systems.
