Interactive Sketch Recognition Approach with Real-time Feedback

In order to promote efficiency and extend applicability of the online synchronous sketch recognition,a sketch recognition algorithm based on incremental intention extraction is presented. Through defining a lag window,the algorithm understands the sketch intention of users on the base of incremental intention extraction.Moreover,the algorithm can update the existing intention sections according to the latest information such that the recognition results are in line with the sketch intention of users. Experiments show the algorithm can recognize various kinds of sketches accurately in real time.
