摘要 采用改进的BP网络分类器对CD4细胞图像进行识别.首先对图像进行了预处理,分析了图像的特征,然后通过增L减R法选择,介绍了BP网络分类器和LM算法的原理,构建了基于LM算法的BP网络分类器,较好地实现了CD4细胞的识别. An improved BP neural network classifier is used to recognize CD4 cell images in this paper. First, the image is preprocessed and the characteristics of CD4 microscopic images are analyzed. Then, the original features are selected by the plus L and take away R method. The principle of BP neural network classifier and LM Algorithm are introduced and a BP neural network classifier based on LM Algorithm is constructed, from which the CD4 cell can be well recognized.
