Fast Stroke Matching by Angle Quantization
Luke Olsen, Faramarz Famil Samavati, Mário Costa Sousa · 2007
Determining similarity of two point sequences (strokes) is a fundamental task in gestural interfaces. Because the length of each stroke is arbitrary, mapping to a fixed-dimension feature space is often done to allow for direct comparison. In this paper, we propose a new feature space based on angle
