On-Line Handwritten Bangla Basic Character Database
Recently,
we have developed a database of online handwritten isolated Bangla characters.
These samples have been collected using WACOM Intuous 2 tablet. The maximum
sampling rate is 200 points per second. No restriction was imposed on the
writers except for specifying rectangular regions for writing each character
sample. Each person was asked to write samples at two to five different points
of time. This is to capture the variation in one's handwriting style that may
occur from one point of time to another. Each sample is stored as a text file
consisting of the (x, y) coordinates and pressure among a few
other information of the pen tip along its trajectory. Here, we considered only
the coordinates of the positions of pen tip having non-zero pressure. The pen
up and pen down situations are identified in terms of zero and non-zero
pressures. A few samples from this database are shown in the following Figure.
