This paper addresses the problem of recovering a super-resolved image from (an) office document image(s) that is/are obtained through document scanner and has/have several texts. We propose a method that enables super-resolution even if we get only one input image. Firstly, text images are extracted from (an) input image(s). Secondly, these text images are classified such that one class has same text images. Finally, super-resolution algorithm is adopted for each class to create a high-resolution text image. Simulation results show that this method can restore sufficient text quality. Also, we exploit a new image-registration algorithm using quadric hyper-surfaces and a fast super-resolution algorithm especially for text images. |
