Re-engineering SORT-based algorithms for low-cost small object tracking from omnidirectional footage
Xin Shu, Meegan Gower, Yvonne Buckley +1
Multi-object tracking (MOT) has advanced rapidly in urban surveillance and autonomous driving, yet many trackers rely on ReID- and transformer-based appearance encoders and are des…
Efficient Dense Matching for Enhanced Gaussian Splatting Using AV1 Motion Vectors
Julien Zouein, Vibhoothi Vibhoothi, François Pitié +1
3D Gaussian Splatting (3DGS) has emerged as a prominent framework for real-time, photorealistic scene reconstruction, offering significant speed-ups over Neural Radiance Fields (Ne…
Leveraging AV1 motion vectors for Fast and Dense Feature Matching
Julien Zouein, Hossein Javidnia, François Pitié +1
We repurpose AV1 motion vectors to produce dense sub-pixel correspondences and short tracks filtered by cosine consistency. On short videos, this compressed-domain front end runs c…
AV1 Motion Vector Fidelity and Application for Efficient Optical Flow
Julien Zouein, Vibhoothi Vibhoothi, Anil Kokaram
This paper presents a comprehensive analysis of motion vectors extracted from AV1-encoded video streams and their application in accelerating optical flow estimation. We demonstrat…
An Empirical Study of Reducing AV1 Decoder Complexity and Energy Consumption via Encoder Parameter Tuning
Vibhoothi Vibhoothi, Julien Zouein, Shanker Shreejith +2
The widespread adoption of advanced video codecs such as AV1 is often hindered by their high decoding complexity, posing a challenge for battery-constrained devices. While encoders…
LiteVPNet: A Lightweight Network for Video Encoding Control in Quality-Critical Applications
Vibhoothi Vibhoothi, François Pitié, Anil Kokaram
In the last decade, video workflows in the cinema production ecosystem have presented new use cases for video streaming technology. These new workflows, e.g. in On-set Virtual Prod…
Demystifying the use of Compression in Virtual Production
Anil Kokaram, Vibhoothi Vibhoothi, Julien Zouein +4
Virtual Production (VP) technologies have continued to improve the flexibility of on-set filming and enhance the live concert experience. The core technology of VP relies on high-r…
Predicting total time to compress a video corpus using online inference systems
Xin Shu, Vibhoothi Vibhoothi, Anil Kokaram
Predicting the computational cost of compressing/transcoding clips in a video corpus is important for resource management of cloud services and VOD (Video On Demand) providers. Cur…
Unravelling the Power of Single-Pass Look-Ahead in Modern Codecs for Optimized Transcoding Deployment
Vibhoothi Vibhoothi, Julien Zouein, François Pitié +1
Modern video encoders have evolved into sophisticated pieces of software in which various coding tools interact with each other. In the past, singlepass encoding was not considered…
