(3)基于RGB的HAR方法也可以用来做pretrained model。缺点主要有:(1)由于RGB数据中存在背景、视点、尺度和光照条件的变化,所以在RGB模态中进行识别通常具有挑战性。(2)RGB视频数据量较大,计算成本较高。图2展示了基于RGB模态数据的HAR方法的主要分类,下面分别对这些方法进行介绍。 图2 基于RGB/光流模态的HAR方法分类...
输入初始化目标框,在下一帧中产生众多候选框(Motion Model),提取这些候选框的特征(Feature Extractor),然后对这些候选框评分(Observation Model),最后在这些评分中找一个得分最高的候选框作为预测的目标(Prediction A),或者对多个预测值进行融合(Ensemble)得到更优的预测目标... Polen: 最全面的一篇视觉跟踪的综述,...
We collected a dataset of daily activities and based on which experiments were performed to compare our HMM-DNN model with both HMM-GMM and HMM-RF. The results illustrated that HMM-DNN outperformed both HMM-GMM and HMM-RF. 展开 关键词: accelerometer activity recognition deep neural networks ...
One of the main challenges in the field of activity recognition is estimating human poses. This has traditionally been done by using a hand-crafted model that requires careful initialization and parameter estimation, but thanks to recent advances in deep learning it’s now possible to use neural ...
