Unknown object detection by training with phrase and region pairs with GLIP

Unknown object detection by training with phrase and region pairs with GLIP


Grounded Language-Image Pre-training

arXiv paper abstract https://arxiv.org/abs/2112.03857



... presents a grounded language-image pre-training (GLIP) model for learning object-level, language-aware, and semantic-rich visual representations.


GLIP unifies object detection and phrase grounding for pre-training.


... GLIP to learn from both detection and grounding data to improve both tasks and bootstrap a good grounding model ... GLIP can leverage massive image-text pairs by generating grounding boxes in a self-training fashion, making the learned representation semantic-rich.


... pre-train GLIP on 27M grounding data, including 3M human-annotated and 24M web-crawled image-text pairs.


The learned representations demonstrate strong zero-shot and few-shot transferability to various object-level recognition tasks.


1) When directly evaluated on COCO and LVIS (without seeing any images in COCO during pre-training), GLIP achieves 49.8 AP and 26.9 AP, respectively, surpassing many supervised baselines ...
