Russian Handwritings Tracked

We created a character dataset by collecting samples from 12 writers. Each writer contributed with letters (lower and uppercase), digits, and words from a pangram that we have not employed in our experiments, but they are included in "extra" folder for each writer in this database. Up to 4 samples have been collected for each pair writer/character, and the total number of samples in this database version is 2812.

Database structure:

scanner.py - character scanning program, dataset collection.
convert2mnist.py - a program for converting a dataset into a mnist-like form. It is intended for an example with the test.
example_using.py - example of a primitive grid for character recognition. It is intended only to demonstrate the consistency of the dataset. When using the dataset, of course, the user can and will use their own, more advanced approaches.
data - folder with dataset.
w_n_m - folder with writer's attempt (in total 37 folders)
[char] - the main file of the symbol track, a text file with a list of coordinates of the form - "x1","y1","x2","y2",...,"xN","yN".
[char]_times - a file with additional information on the track with a list of time in ms between receiving coordinates of points.
[char].png is an auxiliary file - a picture of the symbol as it was visible to the writer. The file is for understanding only.
