HVSBench

HVSBench is a benchmark for evaluating how well multimodal large language models align with human perceptual behavior. It covers human visual system tasks across prominence, subitizing, prioritizing, free-viewing, and searching.

This Hugging Face release packages the divided 10% test subset described in the paper as parquet shards with embedded image bytes. It contains 8,657 question-answer examples and 7,507 unique raw images referenced through the image column. The corresponding paper describes the full HVSBench benchmark with 85,147 multimodal QA pairs across 13 question types and 5 fields.

Dataset Structure

The dataset is uploaded as parquet shards. The image feature contains the image data embedded in parquet, and real_image_path preserves the original relative source path under raw_datasets.

Columns:

• image: raw RGB image embedded in parquet
• index: source row index
• question: benchmark prompt
• question_type: question type ID, Q1-Q13
• answer: ground-truth answer
• answer_type: answer format, such as single_choice, int_number, sorting, or fixation_prediction
• category: benchmark category, such as saliency_rank, salient_instance, or scanpath
• split: original split label
• real_image_path: original relative path under raw_datasets
• origin_dataset: source dataset name
