Does it Really Count? Assessing Semantic Grounding in Text-Guided Class-Agnostic Counting

Giacomo Pacini, Luca Ciampi, Nicola Messina +3

Open-world text-guided class-agnostic counting (CAC) has emerged as a flexible paradigm for counting arbitrary object classes by using natural language prompts. However, current ev…
