Description

A dataset of online handwritten assamese characters by collecting samples from 45 writers is created. Each writer contributed 52 basic characters, 10 numerals and 121 assamese conjunct consonants. The total number of entries corresponding to each writer is 183 (= 52 characters + 10 numerals + 121 conjunct consonants). The total number of samples in the dataset is 8235 ( = 45 183 ). The handwriting samples were collected on an iball 8060U external digitizing tablet connected to a laptop using its cordless digital stylus pen. The data acquisition program consists of a GUI which shows a box on the screen along with other controls. The writers are instructed to write only inside the acquisition box. The acquisition program records the handwriting as a stream of (X, Y) coordinate points using the appropriate pen position sensor along with the pen-up/pen-down switching. No pressure level was recorded. The distribution of the dataset consists of 45 folders (one for each writer) and a Data_Table.pdf file. This file contains information about the character id (ID), character name (Label) and actual shape of the character (Char). Each folder contains 183 text files corresponding to the 183 characters written by a single writer. Each file is named based on the pair (M, N). The text file M.N.txt represents the character with ID M written by the writer with ID N. For instance the file 132.10.txt represents the character with ID 132 written by the writer with ID 10.
