Abstract
An algorithm for text/graphics separation is presented in this
paper. The basic principle of the algorithm is to erase nontext regions
from mixed text and graphics engineering drawings, rather than extract
text regions directly. This algorithm can be used to extract both
Chinese and Western characters, dimensions, and symbols and has few
limitations on the kind of engineering drawings and noise level. It is
robust to text-graphics touching, text fonts, and written orientations
