Research On On-line Handwritten Intelligent Computing System

On-line handwritten intelligent computing is a branch of image processing, its main task is to complete the work to identify and calculate on-line inputted mathematic formula. The direct purpose of research for on-line handwritten intelligent computing systems is to theoretically study and design a system with function of on-line inputting mathematical formula, quickly and accurately identifying and calculating the output. It provides new ways to complete computing tasks to make the computing environment more abundant. In the long run, it supplements computer vision theory and contributes to the ultimate realization of artificial intelligence.Research of on-line handwritten recognition and calculated will start from stroke segmentation, character recognition and structural analysis. We establish the main idea of global optimization that we concatenate the three parts of stroke segmentation, character recognition and structural analysis. The research includes the following aspects: proposing heuristic stroke segmentation method to enhance segmentation rules and reduce the process of character recognition; proposing character recognition method based on linear discriminant analysis and extreme learning machine combination to improve recognition speed and guarantee recognition rate; proposing mathematical formula recognition algorithm based on improved parsing to make a mathematical formula recognition process be broken down into several sub-cycles and finally output results with specific way. That corrects a part of the sequential of strokes, and improves the efficiency of the analysis process.The on-line handwritten intelligent computing system based on the theory of global optimization will realize the function such as on-line handwritten, math formula recognition and computing, which make up the shortage that most of the current theoretical analysis can’t achieve optimal results and achieve the purpose of rapid and accurate on-line handwritten computing. It provides a new and more convenient way to calculate and has a certain research value.
