这就引出了零样本目标检测 (Zero-shot Object Detection) 和开放词汇目标检测 (Open-vocabulary Object Detection) 这两个具有前沿意义的研究方向,即让模型拥有在没有见过特定类别的情况下识别新类型的目标的能力。 由于这两个概念经常存在交叉和混用,本文统一将能够实现零样本检测、目标定位以及通过视觉提示完成少样本...
Our method distills the knowledge from a pretrained open-vocabulary image classification model (teacher) into a two-stage detector (student). Specifically, we use the teacher model to encode category texts and image regions of object proposals. Then we train a student detector, whose region embedd...
for each object in the predefined objects, e.g., racket, use the grad-cam to visulize its activation map. apply proposal generator to get multiple boxes the box with the largest overlap with the activation map is regarded as the pseudo box. 2.2 open vocabulary object detector with pseudo-b...
Open-vocabulary object detection, which is concerned with the problem of detecting novel objects guided by natural language, has gained increasing attention from the community. Ideally, we would like to extend an open-vocabulary detector such that it can produce bounding box predictions based on ...
Open-Vocabulary DETR with Conditional Matching yuhangzang/ov-detr • • 22 Mar 2022 To this end, we propose a novel open-vocabulary detector based on DETR -- hence the name OV-DETR -- which, once trained, can detect any object given its class name or an exemplar image....
前景检测器(Foreground Detector):不需要使用提供的233类类别信息,只使用位置坐标训练一个前景检测器,整个 pipeline 中只有这里进行梯度更新; 提示词工程(prompt engineering):使用大语言模型(LLM)进行半自动化的提示词工程,输入类别 c,给定模板规范,生成更多风格多样的提示词; ...
右边:应用到下游的时候把pretrain时候的GAP改成detector head; :(个人认为是论文中最为核心的部分就是在pretrain的阶段建立起region跟text之间的关系,具体的实现是通过CPE模块对positional embedding进行random 变换得到的,论文中其他的部分例如loss修改等细节就不再介绍了,大家感兴趣的可以再follow原文。

[2024-1-31]:We are excited to launchYOLO-World, a cutting-edge real-time open-vocabulary object detector. TODO YOLO-World is under active development and please stay tuned ☕️! Complete documents for pre-training YOLO-World. COCO & LVIS fine-tuning. ...
Open vocabulary object detection (OVD) aims at seeking an optimal object detector capable of recognizing objects from both base and novel categories. Recent advances leverage knowledge distillation to transfer insightful knowledge from pre-trained large-scale vision-language models to the task of object...
