Abstract
In this paper, we propose the FPGA implementation of a watermarking algorithm in the spatial domain. The paper put emphasis on Quantization Index Modulation based watermarking approach using dither sequences. The cost-effective data embedding algorithm can conceal watermark into original cover image coming from a sensor more rapidly than software implementation and the embedded image is effortlessly transmitted to PC by using proper interface. The obtained results for the algorithm and FPGA implementation are presented and discussed.
