Field Extraction for Form Documents

Abstract

Since form documents play a very important role in various applications, from interpretation is always a good topic in image processing. In this paper, a method for extracting field features of a form document is presented. This method is immune to slant forms with skew angle being less than45 degrees. It can be divided into the following steps: image scanning, connected-component generation, contour tracing, corner extraction, line generation, corner grouping, and line alignment. Experimental results show that this method produces goods results in fast running speed.
