The subject of the graduate qualification work is "The introduction of digital technology for processing handwritten expressions in the construction industry"The purpose of the thesis is to develop a program for processing handwritten mathematical expressions entered by the user. The program must be presented as a service, that is, it must have a standardized interface so that it can be easily implemented in any third-party product. The service must accept as input an image containing a single hand-drawn mathematical expression. The output should be a tree structure that describes this expression and is suitable for further processing.To achieve this goal, the following tasks should be solved:1. Conduct an analysis of the subject area.2. Develop an algorithm that processes symbols and produces a data structure - an expression tree.3. Collect a training sample from handwritten characters.4. Model and implement a neural network that recognizes mathematical symbols.5. Test the project.6. Attach the project to third-party software.In the course of the work, an analysis of the subject area was carried out, a training sample of characters was collected, a neural network was modeled and developed that recognizes these characters, an algorithm was implemented that processes the recognized characters and builds an expression tree based on them.As a result of the work, a service was developed for processing handwritten mathematical expressions. |
