资源介绍:

标注方式上： RefCOCOg采用的是非交互式标注法，选定区域请人标注，再请另外一批人根据标注的expression选择对应的region； RefCOCO和RefCOCO+采用的是双人游戏 (Refer it game)的方式. 数据划分方式上： RefCOCO和RefCOCO+包含train, val, testA, testB。testA的图片包含多个人；testB的图片包含多个除人之外的物体。同一个图片的object-expression样本对要么全在训练集，要么全在验证\测试集。 RefCOCOg包含train, val, test。是按照object进行划分的，同一个图片的object-expression样本对集合可能会在训练集一部分，在验证\测试集另一部分。图片选择上： RefCOCO：图像包含同一类别的多个物体。 RefCOCO+：图像包含同一类别的多个物体，并且expression不能有绝对位置（e.g., left）的词。 RefCOCOg：图像包含同一类别的2-4个物体，覆盖面积超过图片面积的5%
