Handwritten Numeric Digits (HND)

Handwritten numeric digits extracted from public documents. There are 13896 images (28 x 28 pixels) of numeric digits (0-9) with a imbalanced distribution. This dataset was created to do proofs with classification models reuse.

本数据集为从公开文档中提取的手写数字样本集合，包含13896张尺寸为28×28像素的0至9手写数字图像，且类别分布存在不均衡性。构建该数据集旨在用于分类模型复用相关的验证实验。
