Interactive Line Drawing Recognition and Vectorization with Commodity Camera
2014
Proceedings of the ACM International Conference on Multimedia - MM '14
Preserved Fulltext
This paper presents a novel method that interactively recognizes and vectorizes hand-drawn strokes in front of a commodity webcam. ...
By this, we can avoid various stroke recognition ambiguities, enhance the vectorization quality, and recover the stroke drawing order. ...
