HMM-based sketch recognition system:design and optimization
Ding Qiu-lin · Jisuanji yingyong yanjiu · 2011
Newly pen-based interaction technology requires efficient user gesture recognition and user style adaption.This paper built an HMM-based sketch recognition system and used a new method called midpoint-compensation in resampling phase and an improved direction coding method for optimization.The experiment shows that the sketch recognition model can recognizes user gesture efficiently meanwhile with smaller data to represent the gesture and less computation for training the model.
