Extraction of Character String Areas from Color Scenery Image Using Psychological Potential Field

As digital cameras have been used widely, a technology to extract features of character string areas from scenery (nature) image is required. However, it is very difficult to extract character string areas from a complex background of scenery image as compared wit,h a relatively simple background of documentary image. Human can extract of character string areas from scenery image having complex background. Therefore, a fairly high degree of accuracy in the extract.ion of character st,ring areas may be attained by imitating the human visual processing system. In t,his paper we proposed the method to extract charact.er st,ring a r e a from color scenery images using t.he psychological pot,ent,ial field [1],[2] (imitating t.he human visual processing system). We have also executed the experiment and obtained the favorable processing results that are close tjo the human sense and unlikely t,o be affected by amounts of color inform,zt,ion and photographing conditions. And, this met,hod have high degree of accuracy in the extraction of character string areas when it is applied to t,he color scenery image.
