HME100K: A Dataset For Handwritten Mathematical Expression

We introduce the HME100K dataset, a large-scale and real scene dataset suitable for evaluating handwritten mathematical expression recognition task. SAN code is available at here.

Image Collection

The data were collected from tens of thousands of writers who wrote the MEs on papers and uploaded them to an internet application.
