Abstract
This paper proposes a real-time coding system for high-resolution images. The hardware platform mainly consists of FPGA and DSP, which are grouped together in an efficient way. A fast modified SPIHT algorithm is proposed and implemented in the platform. Based on input data rate, this system can adjust the compression rate adaptively. Experimental results show that our proposed compression system meets real-time coding requirement, while the reconstructed image has good visual quality and high peak signal-to-noise rate.
