摘要
提出一种基于DCT域的数字水印算法,并用FPGA硬件实现其中关键部分DCT变换。采用VHDL语言有效设计和实现DCT变换,分析与仿真结果表明:与软件实现相比,用FPGA实现水印算法具有高速实时处理的优点。因此,该设计是一种很有吸引力的硬件实现解决方案。
In this paper,a digital watermarking algorithm based on DCT domain is presented,and the DCT transform, which is the key part of the digital watermarking,is implemented by FPGA harchware.The design and realization of the DCT transform uses the VHDL language.The analysis and simulation results show that FPGA-based digital watermarking algorithm implementation method has the advantage of high speed real-time processing over the software-based watermarking algorithm.The system design becomes a highly attractive solution to hardware realization.
