About

I received my PhD degree at the Faculty of Computer and Information Science, University of Ljubljana in 2021 under the supervision of Assoc. Prof. Matej Kristan, PhD.

My research interests are visual object tracking, video object segmentation, deep learning, pattern recognition and machine learning. In the past I was working on the industrial project for surface quality inspection.

I am a teaching assistant at the Advanced Computer Vision Methods course.

Research

Discriminative correlation filter tracking

We explore online learning of target visual models via discriminative correlation filters. The research spans hand-crafted features and optimization techniques for CPU-based tracking as well as deep learning variants with discriminative feature adaptation and online segmentation.

Tracking transparent objects

We develop new algorithms for tracking transparent objects like glasses, cups or jars.

Visual object tracking performance evaluation

One of the problems of visual tracking evaluation is a lack of a consistent evaluation methodology. This is hampering the cross-paper tracker comparison and faster advancement of the field. In our research we investigate different aspects of tracking evaluation. A continuous effort that is a part of our work is also the Visual Object Tracking Challenge (VOT).

Apparent motion patterns

We propose to go beyond pre-recorded benchmarks with post-hoc annotations by presenting an approach that utilizes omnidirectional videos to generate realistic, consistently annotated, short-term tracking scenarios with exactly parameterized motion patterns..

Drone tracking

The tracking algorithms we developed can be applied to autonomous robots like drones. Here are some results from this research application.

Low-shot counting

The main goal of this research is development of computer-vision-based automated counters that do not require large training datasets, but are adapted to a previously unseen category by using only a few training examples (few-shot), no training examples (zero-shot) or text-based prompts (text-prompt-based).

Dense object counting in underwater imagery

The main goal of this research is development of computer-vision-based automated counters applicable underwater imagery. Such counters are crucial for processing extremely large datasets, vastly reducing the required manual labor and facilitating census orders of magnitude grater than what is possible with standard techniques. The methods leverage learning on specific type of images to maximize a task-specific detection performance.

Computer Vision

January 2019 - December 2024

Computer vision is becoming a focal problem area of artificial intelligence. On the wings of deep learning it has become very powerful tool for solving various problems involving processing of visual information. In the framework of this programme we are addressing several research questions ranging from visual tracking to visual learning for autonomous robots, with a special emphasis on going beyond supervised deep learning.
