Is Tracking really more challenging in First Person Egocentric Vision? Visual object tracking and segmentation are becoming fundamental tasks for understanding human activities in egocentric vision. Recent research has benchmarked state-of-the-art methods and concluded t...

The VISTA benchmark will be released soon. Stay tuned!

(6/7)

These FPV-specific challenges include:
- Frequent object disappearances
- Continuous camera motion altering object appearance
- Object distractors
- Wide field-of-view distortions near frame edges

(5/7)

- Trackers learn viewpoint biases and perform best on the viewpoint used during training.
- FPV tracking presents its specific challenges.

(4/7)

Key takeaways from our study:

- FPV is challenging for state-of-the-art generalistic trackers.
- Tracking objects in human-object interaction videos is difficult across both first- and third-person viewpoints.

(3/7)

We specifically examined whether these drops are due to FPV itself or to the complexity of human-object interaction scenarios.

To do this, we designed VISTA, a benchmark using synchronized first and third-person recordings of the same activities.

Is Tracking really more challenging in First Person Egocentric Vision?

Our new #ICCV2025 paper follows up our IJCV 2023 study (bit.ly/4nVRJw9).

We further investigate the causes of performance drops in object and segmentation tracking under egocentric FPV settings.

In the past weeks we have been around NETI at @utaustin.bsky.social, @vssmtg.bsky.social 2025, and the CVR-CIAN conf. @yorkuniversity.bsky.social, to discuss early findings on modeling object motion in the macaque visual system by deep neural networks. Details to appear soon! @kohitij.bsky.social

Honored to be on the list this year!

We are now live with the 3d Workshop on Computer Vision for Winter Sports @wacvconference.bsky.social #WACV2025.

Make sure to attend if you are around!

This paper contributes to our projects PRIN 2022 EXTRA EYE and Project PRIN 2022 PNRR TEAM funded by European Union-NextGenerationEU.

This work was led by Moritz Nottebaum (stop by his poster!) at the Machine Learning and Perception Lab of the University of Udine

LowFormer achieves significant speedups in image throughput and latency on various hardware platforms, while maintaining or surpassing the accuracy of current state-of-the-art models across image recognition, object detection, and semantic segmentation.

4/6

We used insights from such an analysis to enhance the hardware efficiency of backbones at the macro level, and introduced a slimmed-down version of multi-head self-attention to improve efficiency in the micro design.

3/6

We empirically found out that MACs alone do not accurately account for inference speed.

LowFormer: Hardware Efficient Design for Convolutional Transformer Backbones Research in efficient vision backbones is evolving into models that are a mixture of convolutions and transformer blocks. A smart combination of both, architecture-wise and component-wise is mandatory...

Today at @wacvconference.bsky.social #WACV2025, we present LowFormer, a new family of convolutional-transformer architectures for computer vision that improve efficiency by optimizing running time on hardware rather than minimizing MAC operations.

Is attendance open to YorkU researchers (e.g. postdocs)? Would like a lot to learn from your teaching style!

Did the same a few weeks ago in Toronto. I think this is the best pizza flavor you can get in Canada 😂

YouTube video by Matteo Dunnhofer [WACV 2024] Tracking Skiers from the Top to the Bottom - qualitative examples

The #SkiTB Visual Tracking Challenge at #WACV2025 is open for submissions!

The goal is to track a skier in a video capturing his/her full performance across multiple video cameras, and it is based on our recently released SkiTB dataset.

Would be happy to be added as well :) I am working on visual tracking, currently at YorkU ;)

The outgoing phase of my MSCA project PRINNEVOT has started a few days ago. I am now at the #CentreforVisionResearch of #YorkUniversity.

I am looking forward to the next two years of research at the intersection of computer vision and visual neuroscience! 🤖🧠
