Guided Cross-Component Prediction for RGB Video Coding

2018 Data Compression Conference, 2018
Statistical dependencies among different color components can be exploited to improve the compression efficiency of video coding. In the Range Extensions (RExt) of High Efficiency Video Coding (HEVC) standard, a cross-component prediction tool is adopted.

Dynamic Message Propagation Network for RGB-D and Video Salient Object Detection

ACM Trans. Multim. Comput. Commun. Appl., 2023
Exploiting long-range semantic contexts and geometric information is crucial to infer salient objects from RGB and depth features. However, existing methods mainly focus on excavating local features within fixed regions by continuously feeding forward ...

1000 FPS HDR Video with a Spike-RGB Hybrid Camera

Computer Vision and Pattern Recognition, 2023
Capturing high frame rate and high dynamic range (HFR&HDR) color videos in high-speed scenes with conventional frame-based cameras is very challenging.

RGB-D video content identification

2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013
This paper proposes the first content identification (ID) system for depth video as well as a first hybrid content ID system for synchronized RGB and depth (RGB-D) video. The proposed systems are tested on a public RGB-D dataset. The hybrid system demonstrates significant performance gains over RGB-alone or depth-alone systems, while depth and RGB ...

Bradykinesia Recognition in Parkinson’s Disease via Single RGB Video

ACM Transactions on Knowledge Discovery from Data, 2020
Parkinson’s disease is a progressive nervous system disorder afflicting millions of patients. Among its motor symptoms, bradykinesia is one of the cardinal manifestations.

Effective keyframe extraction from RGB and RGB-D video sequences

2017 Seventh International Conference on Image Processing Theory, Tools and Applications (IPTA), 2017
The rapid increase in digital video content demands effective summarization techniques, specially with the creation of RGBD videos. Keyframe extraction significantly reduces the amount of raw data in a video sequence. In this paper, we present a two-stage (histogram and filtering) keyframe extraction algorithm applicable on RGB and RGBD videos.

Label propagation in RGB-D video

2017 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2017
We propose a new method for the propagation of semantic labels in RGB-D video of indoor scenes given a set of ground truth keyframes. Manual labeling of all pixels in every frame of a video sequence is labor intensive and costly, yet required for training and testing of semantic segmentation methods.

Generative Adversarial Networks for Depth Map Estimation from RGB Video

2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2018
Depth cues are essential to achieving high-level scene understanding, and in particular to determining geometric relations between objects. The ability to reason about depth information in scene analysis tasks can often result in improved decision-making

Action recognition in RGB-D egocentric videos

2017 IEEE International Conference on Image Processing (ICIP), 2017
In this paper, we investigate the problem of action recognition in RGB-D egocentric videos. These self-generated and embodied videos provide richer semantic cues than the conventional videos captured from the third-person view for action recognition. Moreover, they contain both appearance information and 3D structure of the scenes from the RGB modality
