ISGL Online and Offline Character Recognition Dataset

The Intelligent System Group Lab (ISGL) dataset is a dataset of independent Online and Offline handwritten English characters and words comprising of 64 writers, the offline subset of the dataset was acquired through writing on paper and scanning while the online subset was acquired on a digitized tablet integrated to a custom developed acquisition software, the number of stroke, pen up, pen down, pixel position(x,y), and time taken to write were also captured.智能系统组实验室（Intelligent System Group Lab，ISGL）数据集是一类面向独立线上、线下手写英文字符与单词的数据集，其样本覆盖64名书写者。该数据集的线下子集通过在纸张上书写后扫描获取，线上子集则通过搭载定制开发采集软件的数字化手写平板采集，采集内容还涵盖笔画数、抬笔、落笔、像素坐标（x,y）以及书写耗时等信息。
