Performance Comparison of Digital Image Processing Based on CPU and GPU/CUDA |

| Abstract: | Surveying and Mapping System usually has a lot of images to process and Out-door Image Collection System calls for high realtime performance. The result of digital image processing tests on GPU and CPU showed that the performance of digital image processing could be greatly improved by GPU-based parallel computing. GPUbased parallel computing can increase the speed of image pre-processing and image post-processing so that the Surveying and Mapping System becomes more efficient and has high real-time performance. |
