SalBench: A Benchmark for Evaluating Perceptual Capabilities of Vision-Language Models

[💻 Github] [📊 Leaderboard ][[📖 ArXiv Paper](Comming Soon)]

Introduction

We present Saliency Benchmark (SalBench), a novel benchmark designed to assess the capability of Large Vision-Language Models (LVLM) in detecting visually salient features that are readily apparent to humans, such as a large circle amidst a grid of smaller ones. This benchmark focuses on low-level features including color, intensity, and orientation, which are fundamental to human visual processing. Our SalBench consists of images that highlight rare, unusual, or unexpected elements within scenes, and naturally draw human attention. It comprises three novel tasks for evaluating the perceptual capabilities of LVLM: Odd-One-Out Detection, Referring Odd-One-Out, and Visual Referring Odd-One-Out. We perform a comprehensive evaluation of state-of-the-art LVLM using SalBench and our findings reveal a surprising limitation: LVLM struggle to identify seemingly obvious visual anomalies, with even the advanced GPT-4o achieving only 47.6% accuracy on such a simple task. SalBench will be an important step in measuring the capabilities of LVLM that align with the subtle definition of human attention.

Key Tasks in SalBench

1. Salient Object Detection

• Objective: Evaluate the model's ability to identify and segment the most visually important objects in an image.
• Description: The model is tasked with distinguishing salient objects from the background, mimicking human attention.
• Significance: Critical for applications like autonomous driving and medical imaging where detecting key objects is vital.

2. Visual Question Answering (VQA) on Salient Regions

• Objective: Test the model's ability to answer questions that require attention to specific, salient regions of an image.
• Description: The model must extract relevant information from highlighted regions to provide accurate answers.
• Significance: Measures the integration of visual perception and language understanding.

3. Referring Expression Segmentation

• Objective: Assess the model’s capacity to segment objects based on natural language descriptions.
• Description: The model must accurately segment the object referred to by a user-provided textual phrase.
• Significance: Important for human-computer interaction, allowing intuitive control through verbal instructions.
