表示出两帧图像间各个像素点的相对情况，通过反复训练模板能有较高的识别率，研究生时的现代信号处理的作业，基于欧几里得距离的聚类分析，通过虚拟阵元进行DOA估计，是信号处理的基础，利用贝叶斯原理估计混合logit模型的参数，基于负熵最大的独立分量分析。- Between two images showing the relative circumstances of each pixel, Through repeated training IgyWsjylate have higher recognition rate, Modern signal processing jobs when the graduate, Clustering analysis based on Euclidean distance, Conducted through virtual array DOA estimation, Is the basis of the signal processing, Bayesian parameter estimation principle mixed logit model, Based on negative entropy largest independent component analysis.
