Abstract

We report on the recognition from video streams of isolated alphabetic characters and connected cursive textual characters, such as alphabetic, hiragana a kanji characters, drawn in the air. This topic involves a number of difficult problems in computer vision, such as the segmentation and recognition of complex motion from video. We utilize an algorithm called time-space continuous dynamic programming (TSCDP) that can realize both time- and location-free (spotting) recognition. Spotting means that prior segmentation of input video is not required. Each of the reference (model) characters used is represented by a single stroke composed of pixels. We conducted two experiments involving the recognition of 26 isolated alphabetic characters and 23 Japanese hiragana and kanji air-drawn characters. Moreover we conducted gesture recognition experiments based on TSCDP and showed that TSCDP was free from many restrictions imposed upon conventional methods.
