Human Action Analysis with Randomized Trees by Gang Yu, Junsong Yuan, Zicheng Liu

By Gang Yu, Junsong Yuan, Zicheng Liu

This ebook will offer a complete assessment on human motion research with randomized bushes. it is going to disguise either the supervised random bushes and the unsupervised random bushes. while there are enough quantity of categorised facts to be had, supervised random timber offers a quick strategy for space-time curiosity aspect matching. while categorised facts is minimum as with regards to example-based motion seek, unsupervised random bushes is used to leverage the unlabelled information. We describe how the randomized timber can be utilized for motion class, motion detection, motion seek, and motion prediction. we'll additionally describe concepts for space-time motion localization together with branch-and-bound sub-volume seek and propagative Hough voting.

Wu, Z. Zhang, Speeding up spatio-temporal sliding-window search for efficient event detection in crowded videos, in ACM Multimeida Workshop on Events in Multimedia (2009) Chapter 3 Unsupervised Trees for Human Action Search Abstract Action search is an interesting problem for human action analysis, which has a lot of potential applications in industry.

The query samples are drawn from KTH dataset. As there have not been any reported action retrieval results on MSR II dataset, we compare our retrieval results with several previously reported action detection results on this dataset. The evaluation is the same as that for action detection. For the implementations of our random indexing trees, we set the number of trees in a forest N T = 550 and the maximum tree depth to 18. 7 compares the following three strategies on handwaving, handclapping and boxing actions (for the boxing action, we flip each frame in the query video so that we can retrieve the boxing coming from both directions1 ), respectively.

As shown in the first row of Fig. 4, some of the cyan results are focused on a subregion of the action region. But this can be relieved with Hough refinement as indicated in the second row. In short, our action retrieval system can get very good results among the top retrieved subvolumes on various actions types. 4 Action Retrieval on CMU Database CMU database [9] is another widely used database for action analysis. Since the annotation of the actions includes the entire human rather than the action itself (as can be seen from Fig.
