Deep CNN with Skip Connection and Network in Network for Super-Resolving
Blurry Text Images
Abstract
Deep convolutional neural networks (Deep CNN) have achieved hopeful
performancefor single image super-resolution. In particular, the Deep
CNN skip Connection andNetwork in Network (DCSCN) architecture has been
successfully applied to naturalimages super-resolution. In this work we
propose an approach called SDT-DCSCN thatjointly performs
super-resolution and deblurring of low-resolution blurry text
imagesbased on DCSCN. Our approach uses subsampled blurry images in the
input and origi-nal sharp images as ground truth. The used architecture
is consists of a higher numberof filters in the input CNN layer to a
better analysis of the text details. The quantitativeand qualitative
evaluation on different datasets prove the high performance of our
modelto reconstruct high-resolution and sharp text images. In addition,
in terms of computa-tional time, our proposed method gives competitive
performance compared to state ofthe art methods.
