Our database for hand gesture recognition (HGR) contains the gestures from Polish Sign Language ('P' in the gesture's ID) and American Sign Language ('A'). In addition, it some special signs ('S') were included as well. The database was developed as a part of the hand detection and pose estimation project, supported by the Polish Ministry of Science and Higher Education under research grant no. IP2011 023071 from the Science Budget 2012-2013.
The database consists of three series (termed HGR1, HGR2A and HGR2B) which include the subsequent data:
For benchmarking purposes, we publish the results obtained using several different methods developed during our research project. Bayesian classifier was trained using images from the ECU skin database (click here to see the list of images used for training). The classifier was trained in the RGB color space, using 64 bins per channel.
In addition, we have prepared the binaries which implement our methods. The software is available upon request.
In case of any problems or inquries concerning the database, please do not hesitate to contact us.
The file names store the following (e.g. '0_A_hgr2B_id01_1'):
The data are organized into three series acquired in different conditions:
The database is free to use for research, non-commercial purposes, provided that the following papers are cited in the works that exploit the database (here are the BibTeX entries).
