CountGD: Multi-Modal Open-World Counting

Speaker: Niki Amini-Naieni, University of Oxford

CountGD is presented as the first open-world counting model capable of counting any object specified by text only, visual examples only, or both together. It extends the Grounding DINO architecture by adding components that allow object specification through visual examples. This multi-modal capability improves counting accuracy. CountGD is already powering multiple products and has been applied to diverse problems, such as:

* Counting large penguin populations for climate change monitoring

* Counting buildings from satellite images

* Counting seals for conservation purposes1

GorillaWatch: Advancing Gorilla Re-Identification and Population Monitoring with AI

Speaker: Maximilian von Klinski, Hasso-Plattner-Institut

The GorillaWatch project leverages visual AI to improve the monitoring of endangered gorilla populations. Traditionally, scientists rely on labor-intensive manual video labeling. GorillaWatch provides robust re-identification of individual gorillas and generates local population estimates during wildlife encounters, supporting conservation efforts1.

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

Speaker: Markus Hinsche, Thea Care

Skin analysis faces challenges due to inconsistent portrait quality, lighting variations, and the presence of sunscreen or makeup. This talk covers the development of an AI pipeline for skin type classification, which addresses these real-world challenges using:

* Image quality control

* Facial segmentation

* A final classifier trained on curated dermatological features

A Spot Pattern Is like a Fingerprint: Jaguar Identification Project

Speaker: Antonio Rueda Toicen, Voxel51

The Jaguar Identification Project is a citizen science initiative in Porto Jofre, Brazil, engaging the public in conservation. It provides a challenging dataset for fine-grained visual classification algorithms, serving dual purposes:

* Teaching data-centric visual AI

* Contributing directly to conservation efforts for jaguars, a vulnerable species
