in The Open Images Dataset V4: Unified image classification, object detection, and visual relationship detection at scale OpenImages V6 is a large-scale dataset , consists of 9 million training images, 41,620 validation samples, and 125,456 test samples. It is a partially annotated dataset, ...
局部叙事 添加局部叙事标注的动机之一是希望能更充分的研究与利用视觉与语言之间的联系,这通常由添加 Image Captioning (即将图像与人工添加的内容文本描述进行配对) 来完成。不过,Image Captioning存在着诸多局限,其中一个便是缺乏视觉基础,即在进行文本描述时找准文字在图像上的位置。为解决这一问题,先前的一些研究曾采...
这里主要介绍 Open Images v6 数据集的标注文件,Open Images v6 的标注文件是 csv 文件,我们可以用 excel 打开来看一下它的标注细节。标注文件内容示意图如下所示: 可以看到,标注文件包含了 13 个信息,其中重要的信息包括:ImageID(图像索引);LabelName(类别信息);Xmin, Xmax, Ymin, Ymax(标注框位置);以及IsG...
ClassBalanceDataset, 考虑的是该张图片中包含类别最多需要重复的次数,并且计算重复次数的方式也不太一样。例如 image_1 包含 1、2 两个类别,那么如果 1 类别不需要重复,2 类别重复两次,则 Class Aware Sampler 训练中一共训练 image_1 三次;而 ClassBalanceDataset 只会训练两次(因为类别 2 需要重复次数最多)...

Because the intensity of the light was uneven under different wavelengths and the CCD of the camera itself had dark current28, the camera should be processed with dark current calibration and gain calibra- tion (with the whiteboard) before image acquisition. To further improve the signal-to-...

1). First, separate molecular networks were created for each dataset individually, while merging near-identical spectra and only keeping spectra that occur at least twice within the dataset to eliminate non-reproducible MS/MS spectra (Fig. 1, step 1). Spectrum annotations were obtained at the ...
