| Abstract: | A method based on GPU is proposed to extract rock mineral information.With the advantages on parallel computing of the GPU,the core algorithms of rock mineral information extraction are optimized.Because of high spectral characteristics of rock and mineral information extraction algorithms,many performance optimization strategies are proposed,including optimiza-tion process,reduce memory access times and avoiding data access conflicts.Experimental results show that the rock and mineral information could be extracted quickly and efficiently using proposed method,and the maximum speedup is 81 times. |
| Keywords: | hyperspectral remote sensing mineral information extraction GPU parallel optimization |
