Blip Image Captioning Base

🚀 BLIP: Bootstrapping Language-Image Pre-training for Unified Vision-Language Understanding and Generation

Model card for image captioning pretrained on COCO dataset - base architecture (with ViT base backbone).

Pull figure from BLIP official repo

🚀 Quick Start

This model can be used for conditional and un-conditional image captioning. You can follow the usage examples below to get started.

✨ Features

• Flexible Transfer: BLIP is a new VLP framework that can flexibly transfer to both vision - language understanding and generation tasks.
• Effective Use of Noisy Data: It effectively utilizes noisy web data by bootstrapping captions, with a captioner generating synthetic captions and a filter removing the noisy ones.
• State - of - the - Art Results: Achieves state - of - the - art results on a wide range of vision - language tasks, such as image - text retrieval, image captioning, and VQA.
• Strong Generalization: Demonstrates strong generalization ability when directly transferred to video - language tasks in a zero - shot manner.

📚 Documentation

TL;DR

Authors from the paper write in the abstract:

Vision - Language Pre - training (VLP) has advanced the performance for many vision - language tasks. However, most existing pre - trained models only excel in either understanding - based tasks or generation - based tasks. Furthermore, performance improvement has been largely achieved by scaling up the dataset with noisy image - text pairs collected from the web, which is a suboptimal source of supervision. In this paper, we propose BLIP, a new VLP framework which transfers flexibly to both vision - language understanding and generation tasks. BLIP effectively utilizes the noisy web data by bootstrapping the captions, where a captioner generates synthetic captions and a filter removes the noisy ones. We achieve state - of - the - art results on a wide range of vision - language tasks, such as image - text retrieval (+2.7% in average recall@1), image captioning (+2.8% in CIDEr), and VQA (+1.6% in VQA score). BLIP also demonstrates strong generalization ability when directly transferred to videolanguage tasks in a zero - shot manner. Code, models, and datasets are released.
