A uniform framework of representation and structure reconstruction for generic form image

In the paper, we propose a novel uniform representation of generic form, within which three typical categories are defined according to the logical layout from the view point of human vision, which are explicit, semi-explicit, and implicit style form. Under the uniform framework, the different criteria are also defined and carried out on the difference kinds of forms, based on the frame line extraction using single-connected chains. Meanwhile, two subclasses of semi-explicit form, mendable and un-mendable ones, are discovered and can be reconstructed by key points matching and bounding box dilation so that we can deal with a number of variations of form structure. The experimental results have shown that our proposed framework is effective and reasonable for layout analysis and structure reconstruction.
