Online handwriting is formed by a combination of horizontal and vertical trajectories. If these trajectories are treated separately, new recognition methods are emerged. In contrast, one classifier is often used to recognize handwriting. In this work, some features for x(t) and y(t) signals were proposed and used to make two separate classifiers. After initial recognition by these classifiers, their results were fused for final recognition. Using HMM classifiers and simple product rule for decision fusion, the recognition results of 42 classes of Farsi subwords showed promising achievements.
► New features of separated horizontal and vertical trajectories of online handwriting are introduced.
► Decision fusion, based on x(t) and y(t) trajectories, is investigated to recognize online Farsi subwords and shows promising results.
► For very few classes where decomposing ‘x–y’ yields a very plain x(t) or y(t) signals, the recognition rate of the fusion becomes very low.
