Robust stereo matching for document images using parameter selection of text-line extraction

In this paper we present a novel method for automatic text-line parameter selection for stereo image pairs. The parameters are selected such that correspondence between the same content in a stereo pair is maximized. Automatic parameter selection has been carried out by establishing robust text-line correspondence which is also a contribution of the presented work. The proposed method is applied to one text-line extraction algorithm as a proof of concept. The results are compared with the ground truth to show the validity of the method.
