摘要: Abstract An online algorithm capable of recognizing hand-sketched symbols such as those used in flowcharts is presented. The requires no indication symbol segmentations and restrictions on the stroke sequence symbols. has three steps: (1) candidate figure extraction for each based a graph search distance calculation between figures reference patterns, (2) selection which minimizes total sum these distances, (3) connection rules application. A recognition test performed 100 block diagrams produced rate 96.1%.
