3D Layout Propagation to Improve Object Recognition in Egocentric Videos
[chapter]
2015
Lecture Notes in Computer Science
Preserved Fulltext
A common initial step in those settings is the estimation of the 3D layout of the scene. ...
Our experiments demonstrate how this layout information can be used to improve detection tasks useful for a human user, in particular sign detection, by easily rejecting false positives. ...
Method evaluation
Improving object recognition tasks This subsection shows results on object recognition tasks, poster detection in this case, using an egocentric vision dataset. ...

We believe our work points to an exciting research direction in the intersection of egocentric vision, and 3D scene understanding. ...
To evaluate our model, we conduct extensive experiments on a newly collected egocentric video dataset, in which both human naturalistic actions and photo-realistic 3D environment reconstructions are captured ...
This is the first activity recognition dataset to include both egocentric videos and high-quality 3D environment reconstructions. ...

To enable such a capability, we design a new egocentric representation, which we call ECO (Egocentric COgnitive map). ...
As a proof-of-concept, we use ECO to localize a camera within real-world scenes---various grocery stores---and demonstrate performance improvements when compared to existing semantic localization approaches ...
Since the bounding box's cor- ners are specified in 3D, these labels are easily propagated to the rest of the images in the reconstructed batch. Thus, 1 image labels 200 others. ...

Second, objects' 3D locations are explicitly incorporated into GCN to better model egocentric interactions. ...
Third, to implement ego-stuff interaction in GCN, we propose a MaskAlign operation to extract features for irregular objects. ...
Given a video segment, our model applies 3D convolutions to extract visual features followed by two branches: RoIAlign is employed to extract object features from object bounding boxes and MaskAlign is ...

Egocentric activity recognition is one of the most challenging tasks in video analysis. It requires a fine-grained discrimination of small objects and their manipulation. ...
In this paper we propose LSTA as a mechanism to focus on features from relevant spatial parts while attention is being tracked smoothly across the video sequence. ...
However, the performance of deep learning action recognition from videos is still not comparable to the advances made in object recognition from still images [12] . ...

HOI4D consists of 2.4M RGB-D egocentric video frames over 4000 sequences collected by 4 participants interacting with 800 different object instances from 16 categories over 610 different indoor rooms. ...
In a simple scene, the object interacted with is not obscured by surrounding objects, and the variety of camera views in the video is small to improve consistency across frames. ...
