Visual Detection of Business Cards: Segmentation
Technical Report, 2016
This study explores Graph Cut method for the segmentation of business cards captured from a sequence of images. The process of segmentation is needed as a part of an application for detection and recognition of business cards. We explore Graph Cut method in detail, and show it can be applied to business card segmentation. We show how in Graph Cut method foreground and background regions can be successfully initialized using business card key-point detector from our previous study. Furthermore, we show how a sequence of images can be used to improve foreground/background initialization and how by merging multiple frames final segmentation can be improved. We demonstrate our proposed approach on a set of four business cards sequences, using two textured and two nontextured business cards.
