Feature Aggregation based Siamese Network for visual tracking

针对于目标跟踪任务的:基于特征融合技术的孪生网络

简介:本次课题算法采用基于空间位置特异性卷机块算法,首先是利用经典的Siamese网络框架提取出视频序列中相邻两帧,及序列首帧图像的CNN特征,然后对深层CNN特征进行融合kernel预测操作。用所采集到的融合kernel对目标帧特帧进行空间可变性卷机操作,得到可传播的特征量。利用适应性权重计算,将该传播特征与原帧特征相融合,进而完成特征融合的目标。最后,对融合后的优质特征进行经典的RPN目标检测算法的变形算法,得到target的位移,尺度变化信息输出。网络整体采用端到端批训练,且采用Pytorch框架结合CUDA技术进行实验。

框架:pytorch 1.0.0 with CUDA 9.0/ CUDNN

python:2.7
