An Efficient Primitive-Based Method to Recognize Online Sketched Symbols with Autocompletion

Table 3

The comparison with the image-based method in COAD dataset.

Methods	Symbols	Top 1 (%)	Top 3 (%)
Image-based; [5]	Partially drawn symbols	54.94	97.08
	Fully completed symbols	79.83	99.27
Proposed	Partially drawn symbols	83.57	98.90
	Fully completed symbols	75.60	85.53

The accuracy of image-based method comes from [5] when confidence threshold is set to 0.
