LipiTk: DCT 1.0.1

Data Collection Tool (DCT) v1.0.1

Overview

The data collection tool (DCT) provides a user interface to create handwriting datasets by collecting handwriting data samples from different writers. Given the script and the data elements to be collected, writers contribute to the dataset by giving their handwriting samples. The output of the tool is a set of UNIPEN files organized in a directory structure, containing writer profiles, collection procedure details and the digital ink.

Known Issues

Clicking the “Change configuration” button results in the loss of all the writer information entered information in the edit . The configuration details should be changed only by the supervisor. The process of data collection starts by changing the configuration details which is done by the supervisor. So the writer information should be entered only after the configuration changes have been done.
Incase the user presses the next button by chance without completing the current symbols/words, there is no provision to go back, ie editing the samples given before is not possible.
