Isolated Handwritten Telugu Character Dataset

This dataset contains approx 270 samples of each of 166 Telugu "characters" written by native Telugu writers. The data was collected using Acecad Digimemo electronic clipboard devices using the Digimemo-DCT application.  The data is in standard UNIPEN format.

An offline version of the data is also available in the form of bi-level TIFF images, generated from the online data using simple piecewise linear interpolation with a constant thickening factor applied.

The data is available only for research use.
