CountingDINO: A Training-free Pipeline for Class-Agnostic Counting using Unsupervised Backbones

Giacomo Pacini, Lorenzo Bianchi, Luca Ciampi +3

Class-agnostic counting (CAC) aims to estimate the number of objects in images without being restricted to predefined categories. However, while current exemplar-based CAC methods…

Talking to DINO: Bridging Self-Supervised Vision Backbones with Language for Open-Vocabulary Segmentation

Luca Barsellotti, Lorenzo Bianchi, Nicola Messina +5

Open-Vocabulary Segmentation (OVS) aims at segmenting images from free-form textual concepts without predefined training classes. While existing vision-language models such as CLIP…

The devil is in the fine-grained details: Evaluating open-vocabulary object detectors for fine-grained understanding

Lorenzo Bianchi, Fabio Carrara, Nicola Messina +2

Recent advancements in large vision-language models enabled visual object detection in open-vocabulary scenarios, where object classes are defined in free-text formats during infer…
