A FRACTAL JUSTIFICATION OF THE NORMALIZATION STEP FOR ONLINE HANDWRITING RECOGNITION

n this paper is presented an example of the use of fractal approaches in the field of online handwriting processing. The adaptation of the box counting method to the computation of online handwriting fractal dimension is presented. The influence of different parameters is studied. This allows understanding why the value of the proposed parameter is invariant towards the tablet or the speed or the writing size. The study of the transforms that have been chosen in REMUS software allows seeing that they match quite well the quantitative results obtained with fractal methods. Then, a posteriori, in a theoretical way, this confirms the value of the methods involved.
