摘要: With the growing popularity of pen-based and touch-based devices such as Apple's iPad Samsung's Galaxy Tablet, handwriting has become an important input method. Although recognition for text contents mathematical formulae are well-supported in these devices, recognizing handwritten chemical expressions is still very challenging due to its complex spatial structure. In this research, we focus on symbol which essential accurate expression recognition. particular, propose online hybrid Support Vector Machine - Elastic Matching (SVM-EM) approach Based proposed structural analysis, have implemented system iOS platform. paper, present our SVM-EM evaluate it with several users verify promising performance a real application.
