| Abstract(in English) | A mathematical expression consists of characters on base line and subscript expressions which are attached to them except some parts of mathematical expressions as matrix and commutative diagram. In order to extract mathematical symbol on the base line poperly. We propose a method that divides the given mathematical expression into some regions using features of symbols such as integration, summation, square root, fraction line and parenthesis so that divided regions are the level relation. For each divided mathematical expression, recognition of the subscript expression and horizontal decomposition is carried out. This process is repeated until the parent character, namely the number of the characters on the base line in the noticed mathematical expression becomes only one. |
