摘　　要：本文基于支持向量机(SVM)对CD4细胞图像进行了分析识别。在样本数较少和缺乏先验知识的情况下,采用改进的平行栅格搜索算法和交叉验证算法训练并确定分类器参数,提高了分类器性能。实验结果表明,基于支持向量机的分类器的识别率为95%,优于Fisher分类器和BP网络。A method to analyse and recognize the microscopic CD4 cell image based on support vector machines （SVM） is introduced with a small sample size and less prior knowledge in this paper. The method uses an improved parallel grid search algorithm to choose the parameters of the SVM classifier, and employs cross validation to test the performance of SVM classification. Using this new method, an accuracy of 95% has been obtained in the classification of the CD4 cell images, suggesting that the SVM approach is better than the Fisher classifier and the BP neural networks.
