Dear colleagues and friends,
Flying is one of the most beautiful dreams and we had such an beautiful meeting where our dear colleague Drd. Ing. Sebastian Mocanu presented a paper that combines AI with the real world based on drones, namely "A Sim-to-Real Deep Learning-based Framework for Autonomous Nano-drone Racing".
Our meeting was completed by the fantastic demonstration of drone flight made by our group coordinator Prof. Dr. Marius Leordeanu.

Dear colleagues and friends,
Tomorrow I will present you a paper that combines AI with the real world based on drones, namely "A Sim-to-Real Deep Learning-based Framework for Autonomous Nano-drone Racing". This is about a small drone that managed to win the Nanocopter AI Challenge at the International Micro Air Vehicles 2022, being trained only on simulated data. The paper was accepted at IEEE Robotics and Automation Letters (RAL).

Dear colleagues and friends,
Good things are the ones who makes us happy and research is our source of inspiration, work and happiness!
Our dear colleague Drd. Ing. Dragos Costea is one of those researchers with this beautiful passion and joy for sharing their knowledge and his presentation from our weekly meeting at Bucharest Computer Vision Reading Group was again an wonderful experience for all of us!
During our meeting Dragos presented another monocular depth estimation (MDE) method. Starting from a pre-trained image generation model (Stable DIffusion v2), the authors propose a fine-tuning protocol for obtaining new representations. With only 74K synthetic depth images (HyperSim + Virtual KITTI), I get state-of-the-art zero shot MDE results on KITTI, NYUv2, ETH3D.

20 February 2024
Dear colleagues and friends,
Tomorrow I propose to discuss a work that aims to build video-language models capable of solving various tasks (i.e. video captioning, video question answering, text-video retrieval and event prediction).
The authors propose a general method that does not require training and uses image-language models together with an LLM. The method obtains, in the fewshot context, very good results, even close to other strongly pre-trained models.

30 January 2024
Dear colleagues and students,
After discussing multimodal transformers and unsupervised learning, it's time to explore in more detail methods that try to bring information from video and text into the same space. The work that Drd. Ing. Mihai Masala will present tomorrow, 30 January proposes the adaptation of the methods used for the alignment of images and texts (CLIP) to understand the temporal information in videos. Thus, using a relatively small model, they manage to obtain state-of-the-art results on three tasks (captioning, video question answering and retrieval) in front of much larger models that were trained on significantly more data.

Dear colleagues and students,
Now the time has come to resume the discussions from our Bucharest Computer Vision Reading Group and which, from the feedback we received from you but also from what I felt, turned out to be really useful and interesting.
I propose now to go a little in another direction, but also in the area of unsupervised learning, this time on the topic of unsupervised semantic segmentation. There are very few works in the literature that seriously attack the problem of unsupervised segmentation at the semantic level - this is also one of the most difficult problems in learning.
How do we learn about object classes without having human annotations?
How do we learn about new classes of objects, about which we did not know before?
The problem is certainly general enough to go beyond the field of computer vision.
The work that I will present and that will lay the foundations for this discussion, I hope as captivating as possible, is:
Cho, Jang Hyun, Utkarsh Mall, Kavita Bala, and Bharath Hariharan.
