When and Where

• May 20, 2025
• 6:30 PM to 8:30 PM CET | 9:30 AM to 11:30 AM Pacific
• Workshops are delivered over Zoom

About the Workshop

Join us for a 12-part, hands-on series that teaches you how to work with images, build and train models, and explore tasks like image classification, segmentation, object detection, and image generation. Each session combines straightforward explanations with practical coding in PyTorch and FiftyOne, allowing you to learn core skills in computer vision and apply them to real-world tasks.

In this session, we’ll explore image generation techniques using diffusion models. Participants will build a U-Net-based model to generate MNIST-like images and then inspect the generated outputs with FiftyOne.

These are hands-on maker workshops that make use of GitHub Codespaces, Kaggle notebooks, and Google Colab environments, so no local installation is required (though you are welcome to work locally if preferred!)

CountGD: Multi-Modal Open-World Counting

We propose CountGD, the first open-world counting model that can count any object specified by text only, visual examples only, or both together. CountGD extends the Grounding DINO architecture and adds components to enable specifying the object with visual examples. This new capability – being able to specify the target object by multi-modalites (text and exemplars) – lead to an improvement in counting accuracy. CountGD is powering multiple products and has been applied to problems across different domains including counting large populations of penguins to monitor the influence of climate change, counting buildings from satellite images, and counting seals for conservation.

This Gets Under Your Skin – The Art of Skin Type Classification

Skin analysis is deceptively hard: inconsistent portrait quality, lighting variations, and the presence of sunscreen or makeup often obscure what’s truly “under the skin.” In this talk, I’ll share how we built an AI pipeline for skin type classification that tackles these real-world challenges with a combination of vision models. The architecture includes image quality control, facial segmentation, and a final classifier trained on curated dermatological features.

A Spot Pattern Is like a Fingerprint: Jaguar Identification Project

The Jaguar Identification Project is a citizen science initiative actively engaging the public in conservation efforts in Porto Jofre, Brazil. This project increases awareness and provides an interesting and challenging dataset that requires the use of fine-grained visual classification algorithms. We use this rich dataset for dual purposes: teaching data-centric visual AI and directly contributing to conservation efforts for this vulnerable species.

DreamBlend: Advancing Personalized Fine-tuning of Text-to-Image Diffusion Models

Given a small number of images of a subject, personalized image generation techniques can fine-tune large pre-trained text-to-image diffusion models to generate images of the subject in novel contexts, conditioned on text prompts. In doing so, a trade-off is made between prompt fidelity, subject fidelity and diversity. As the pre-trained model is fine-tuned, earlier checkpoints synthesize images with low subject fidelity but high prompt fidelity and diversity. In contrast, later checkpoints generate images with low prompt fidelity and diversity but high subject fidelity. This inherent trade-off limits the prompt fidelity, subject fidelity and diversity of generated images. In this work, we propose DreamBlend to combine the prompt fidelity from earlier checkpoints and the subject fidelity from later checkpoints during inference. We perform a cross attention guided image synthesis from a later checkpoint, guided by an image generated by an earlier checkpoint, for the same prompt. This enables generation of images with better subject fidelity, prompt fidelity and diversity on challenging prompts, outperforming state-of-the-art fine-tuning methods.

Robust Multi-Class Anomaly Detection under Domain Shift

Robust multi-class anomaly detection under domain shift is a fundamental challenge in real-world scenarios, where detectors should distinguish different types of anomalies despite significant distribution shifts. Traditional approaches often struggle to generalize across domains and handle inter-class interference. ROADS addresses these limitations through a prompt-driven framework that combines a hierarchical class-aware prompt mechanism with a domain adapter to jointly encode discriminative, class-specific prompts and learn domain-invariant representations. Extensive evaluations on the MVTec-AD and VISA datasets show that ROADS achieves superior performance in both anomaly detection and localization, particularly in out-of-distribution settings.

What Remains Unsolved in Computer Vision? Rethinking the Boundaries of State-of-the-Art

Despite rapid progress and increasingly powerful models, computer vision still struggles with a range of foundational challenges. This talk revisits the “blind spots” of state-of-the-art vision systems, focusing on problems that remain difficult in real-world applications. I will share insights from recent work on multi-object tracking—specifically cases involving prolonged occlusions, identity switches, and visually indistinguishable subjects such as identical triplets in motion. Through examples from DragonTrack and other mehtods, I’ll explore why these problems persist and what they reveal about the current limits of our models. Ultimately, this talk invites us to look beyond benchmark scores and rethink how we define progress in visual perception.

LLAVIDAL: A Large LAnguage VIsion Model for Daily Activities of Living

Current Large Language Vision Models trained on web videos perform well in general video understanding but struggle with fine-grained details, complex human-object interactions (HOI), and view-invariant representation learning essential for Activities of Daily Living (ADL). In this talk, I will introduce a foundation model: LLAVIDAL catered towards understanding ADL and the tricks to train such models.
