MS COCO 数据集学习笔记(Common Objects in COntext) 一、数据来源 COCO中图片资源均引用自Flickr图片网站 二、数据集创建目的 进行图像识别训练,主要针对以下三个方向: (1)object instances (2)object keypoints (3) image captions 每个方向均包含训练和验证集两个标注文件 三、标注体结构 三个方向均共享基本类型...
和ImageNet对比,COCO有更少类别,但每个类别有更多实例,更有利于目标的定位 和ImageNet、VOC、SUN相比,该数据集每个类别都有更多实例,更关键的是每张图中实例更多,有利于学习目标间的关系 和ImageNet相比、VOC相比,该数据集每张图里的实例更多;SUN一张图里的实例则比该数据集高,但整体上数据集中的实例更少。 相...
common objects in their natural context. Objects are labeled using per-instance segmentations to aid in precise object localization. Our dataset contains photos of 91 objects types that would be easily recognizable by a 4 year old. With a total of 2.5 million labeled instances in 328k images,...

COCO数据集:本数据集包含了91种物体类型的图像,这些物体类型能够被4岁大小的孩子豪不费力的识别出来。数据集有32.8万张图片,包含有250万个标注实例。 标注工具:Microsoft自研 类别确定 使用多个数据源来建立顶层物体类别: 1、首先联系PASCAL VOC数据集的类别, 2、1200种最经常见到的视觉可分辨的物体的一个子集(来自...
We present a new dataset with the goal of advancing the state-of-the-art in object recognition by placing the question of object recognition in the context of the broader question of scene understanding. This is achieved by gathering images of complex ev
