CNFOOD-241
收藏资源简介:
该数据集名为CNFOOD-241,是公开可用的食品数据集中图片尺寸最为统一的一个,包含了近二十万张尺寸均为600×600的图片。该数据集被划分为训练集(119,514张图片)、验证集(51,354张图片)和测试集(20,943张图片)。数据集的归一化熵显示,类别之间存在较大不平衡性,这增加了其挑战性。总的来说,该数据集涵盖了大约200,000张图片,分布在241个类别中,其任务是进行图像分类。
The dataset designated as CNFOOD-241 is one of the publicly available food datasets with the most consistent image dimensions. It contains nearly 200,000 images, all with a fixed resolution of 600×600. The dataset is split into three subsets: a training set with 119,514 images, a validation set with 51,354 images, and a test set with 20,943 images. The normalized entropy of the dataset reveals significant class imbalance, which increases the difficulty of the task. Overall, this dataset covers approximately 200,000 images across 241 categories, and its target task is image classification.
