| Abstract: | The amount of a SAR image is very large usually,meanwhile,the ordinary recognition algorithm is complex and time-consuming.Aimed to solve this jam,a kind of target classification method of SAR image based on OpenMP is proposed.Firstly,the model-template based recognition algorithm is analyzed.Secondly,the OpenMP is applied to build the parallel calculation frame of SAR image target classification method.Finally,the tests are completed by classifying 3 kinds of objects.The test results show that the processing speed is improved by 8 times,and the proposed method is available. |
