中文摘要:针对线性判别分析只能提取线性特征而不能描述非线性特征的缺点,采用将核函数和Fisher判别分析方法的可分性结合起来的核Fisher判别分析的方法对视频中的运动目标进行自动分类,运动目标包含人、汽车和宠物三类。该方法取得了较好的分类效果,且在查全率、查准率和F1 -Measure获得了满意的性能。 |

Classification of Moving Targets in Video Based on the Kernel Fisher Discriminant Analysis |
|

Abstract:In order to overcome the shorts of linear discriminant analysis, which can only extract linear features and can not describe nonlinear characteristics, the Kernel Fisher Discriminant Analysis algorithm, which combines the kernel learning and the separation of linear discriminant analysis, was adopted to automatically classify the moving objects in video. The objects include three categories: people, cars and pets. The method has obtained satisfying performance both in this system and in the recall, precision and F1-score. |
