What we're about

This virtual group is for data scientists, machine learning engineers, and open source enthusiasts who want to expand their knowledge of computer vision and complementary technologies. Every month we’ll bring you two diverse speakers working at the cutting edge of computer vision.

What’s computer vision? It’s how systems can derive meaningful information from digital images, videos and other visual inputs — and how they can take actions or make recommendations based on that information.

Use cases for computer vision include: autonomous vehicles, facial recognition, inventory management, medical imaging and more.

Redefining State-of-the-Art with YOLOv5 and YOLOv8

In recent years, object detection has been one of the most challenging and demanding tasks in computer vision. YOLO (You Only Look Once) has become one of the most popular and widely used algorithms for object detection due to its fast speed and high accuracy. YOLOv5 and YOLOv8 are the latest versions of this algorithm released by Ultralytics, which redefine what "state-of-the-art" means in object detection. In this talk, we will discuss the new features of YOLOv5 and YOLOv8, which include a new backbone network, a new anchor-free detection head, and a new loss function. These new features enable faster and more accurate object detection, segmentation, and classification in real-world scenarios. We will also discuss the results of the latest benchmarks and show how YOLOv8 outperforms the previous versions of YOLO and other state-of-the-art object detection algorithms. Finally, we will discuss the potential for this technology to "do good” in real-world scenarios and across various fields, such as autonomous driving, surveillance, and robotics.


Glenn Jocher is founder and CEO of Ultralytics. In 2014 Glenn founded Ultralytics to lead the United States National Geospatial-Intelligence Agency (NGA) antineutrino analysis efforts, culminating in the miniTimeCube experiment and the world's first-ever Global Antineutrino Map published in Nature. Today he's driven to build the world's best vision AI as a building block to a future AGI, and YOLOv5, YOLOv8, and Ultralytics HUB are the spearheads of this obsession.

Plug-and-Play Diffusion Features for Text-Driven Image-to-Image Translation

Large-scale text-to-image generative models have been a revolutionary breakthrough in the evolution of generative AI, allowing us to synthesize diverse images that convey highly complex visual concepts. However, a pivotal challenge in leveraging such models for real-world content creation tasks is providing users with control over the generated content. In this paper, we present a new framework that takes text-to-image synthesis to the realm of image-to-image translation -- given a guidance image and a target text prompt, our method harnesses the power of a pre-trained text-to-image diffusion model to generate a new image that complies with the target text, while preserving the semantic layout of the source image. Specifically, we observe and empirically demonstrate that fine-grained control over the generated structure can be achieved by manipulating spatial features and their self-attention inside the model.


Michal Geyer and Narek Tumanya are Masters students at the Weizmann Institute of Science in the Computer Vision department.

Re-annotating MS COCO, An Exploration of Pixel Tolerance

The release of the COCO dataset has served as a foundation for many computer vision tasks including object and people detection. In this session, we’ll introduce the Sama-Coco dataset, a re-annotated version of COCO focused on fine-grained annotations. We’ll also cover interesting insights and learnings during the annotation phase, illustrative examples, and results of some of our experiments on annotation quality as well as how changes in labels affect model performance and prediction style.


Jerome Pasquero is Principal Product Manager at Sama. Jerome holds a Ph.D. in electrical engineering and is listed as inventor on more than 120 US patents along with published over 10 peer-reviewed journal and conference articles. Eric Zimmermann is an Applied Scientist at Sama helping to redefine annotation quality guidelines. He is also responsible for building internal curation tools which aim to improve the process on how clients and annotators interact with their data.

Reverse Image Search for Ecommerce Without Going Crazy

Traditional full-text-based search engines have been on the market for a while and we are all currently trying to extend them with semantic search. Still, it might be more beneficial for some ecommerce businesses to introduce reverse image search capabilities instead of relying on text only. However, both semantic search and reverse image may and should coexist! You may encounter common pitfalls while implementing both, so why don't we discuss the best practices? Let's learn how to extend your existing search system with reverse image search, without getting lost in the process!

MARLIN: Masked Autoencoder for Facial Video Representation LearnINg

This talk proposes a self-supervised approach to learn universal facial representations from videos, that can transfer across a variety of facial analysis tasks such as Facial Attribute Recognition (FAR), Facial Expression Recognition (FER), DeepFake Detection (DFD), and Lip Synchronization (LS). Our proposed framework, named MARLIN, is a facial video masked autoencoder, that learns highly robust and generic facial embeddings from abundantly available non-annotated web crawled facial videos. As a challenging auxiliary task, MARLIN reconstructs the spatio-temporal details of the face from the densely masked facial regions which mainly include eyes, nose, mouth, lips, and skin to capture local and global aspects that in turn help in encoding generic and transferable features. Through a variety of experiments on diverse downstream tasks, we demonstrate MARLIN to be an excellent facial video encoder as well as feature extractor, that performs consistently well across a variety of downstream tasks including FAR (1.13% gain over supervised benchmark), FER (2.64% gain over unsupervised benchmark), DFD (1.86% gain over unsupervised benchmark), LS (29.36% gain for Frechet Inception Distance), and even in low data regime.
