Design Of Multi-Spectral Images Real-Time Segmentation System

In order to realize the real-time segmentation processing of multi-spectral images in practice, a real-time multi-spectral images segmentation system composed of four TMS320C6455 DSPs, two Virtex-4(V4 XC4VLX80) FPGAs and one Virtex-2 Pro(V2 Pro20) FPGA is designed. Through the optimization of the cooperation processing of the multi-DSP and multi-FPGA, the parallel multi-task processing ability of the DSPs and the effective interface coordination ability of the FPGAs in the built system are used fully. In order to display the processing ability, the segmentation test experiments of 10 spectra visible images, with 1024x1024, segmented by the Multi-scale Image Segmentation Method, was done in the built multi-spectral images segment system. The experiment results prove that the multi-DSP and multi-FPGA multi-spectral images processing system designed in this paper satisfies the real-time processing requirement in engineering practice.
