PixelProse Dataset
</div>
<h1>
PixelProse<br/><span>Dataset</span>
</h1>
<p class="hero-subtitle">
PixelProse is a large-scale dense image captioning dataset, containing detailed textual descriptions of over 16 million images, each accompanied by rich visual content descriptions, suitable for training visual-language models and image understanding research.
Dataset Highlights
A large-scale dense image description dataset that provides a solid foundation for visual-language model research
Dense Descriptions
Each image is accompanied by a detailed textual description of visual content, covering multi-layered information such as scenes, objects, attributes, relationships, etc., far exceeding the information density of brief titles.
Multi-source Images
Image sources cover multiple public datasets and internet resources, encompassing a rich variety of visual domains including natural scenes, people, animals, architecture, art, etc.
Ultra-large Scale
Contains over 16 million images and their dense descriptions, making it one of the largest open dense image description datasets, meeting the needs for large-scale model training.
High-quality Annotations
The descriptive texts are carefully generated and quality-checked to ensure semantic accuracy and completeness of descriptions, providing reliable supervisory signals for model training.
Visual-Language Alignment
Precise pairing of images and textual descriptions, naturally suitable for research directions such as visual-language pre-training, image-text alignment, and cross-modal representation learning.
Open Research Use
The dataset is released under an open license, supporting academic research and non-commercial use, promoting the development of open science in the field of visual-language understanding.
Applicable Scenarios
From model pre-training to downstream tasks, covering the entire chain of visual-language research
Visual-Language Model Training
As pre-training data for large-scale visual-language models (VLM), enhancing the model's image understanding and description generation capabilities
Image Description Generation
Training and evaluating image captioning models to generate accurate and detailed image description texts
Visual Question Answering
Utilizing rich image descriptions to build visual question answering (VQA) training data, enhancing the model's reasoning ability regarding visual content
Image Retrieval
Building a text-image retrieval system based on dense descriptions, achieving precise cross-modal retrieval from text to image and image to text
Data Preview
The following are example entries from the dataset, each record contains an image URL and its corresponding dense description text

"caption": "A golden retriever sits on a wooden dock by a calm lake at sunset. The dog's fur is illuminated by warm orange light, and its tongue hangs out happily. Behind the dog, the lake reflects the pink and purple hues of the sky. Tall pine trees line the far shore, their silhouettes dark against the colorful horizon. A small red canoe is tied to the dock on the left side of the frame.
The wooden planks of the dock show signs of weathering, with some moss growing between the cracks.",
