基于用户建模的手绘草图识别

在线草图识别包括预处理、特征提取、图形规整和用户建模等几个方面的问题。其中用户建模是手绘草图识别的核心和关键问题。提出了一种在线草图识别用户建模方法,方法用动态用户建模技术进行笔划和复杂图形的识别。方法采用增量决策树记录草图的笔划构成及其手绘过程,实现对复杂手绘草图的用户建模和在线识别。实验表明所提出的方法不仅能得到较好的检索结果,而且具有较好的用户适用性

Sketchy Graphic Recognition Based on User Modeling

On-line sketchy graphic recognition includes pretreatment,feature extraction,graphic regularization,and user modeling. User modeling is the core and key procedure of sketchy graphic recognition. In this paper,an user modeling method for on-line sketchy graphic recognition is proposed; dynamic user modeling is applied to realize recognition of sketches and complex graphics. With this method,incremental decision tree is used to collect and record the sketching strokes and temporal orders of the sketches,in or...
