HASYv2 - Handwritten Symbol database

Content

HASY contains 32px x 32px images of 369 symbol classes. In total, HASY contains over 150,000 instances of handwritten symbols.

See "The HASYv2 dataset" paper (https://arxiv.org/abs/1701.08380) for more information.

HOW HASY WAS CREATED

HASY is derived from the HWRT dataset which was first used and described in [Tho14]. HWRT is an on-line recognition dataset, meaning it does not contain the handwritten symbols as images, but as point-sequences. Hence HWRT contains strictly more information than HASY. The smaller dimension of each recordings bounding box was scaled to be 32 px. The image was then centered within the 32 px × 32 px bounding box
