Based on experimental studies, was revealed that existing OCR systems cannot cope with complex perspective and geometric distortions that arise during ...

Information technology and a new method involving the mathematical raising of straightened text lines on the image and heterogeneous distortion correction ...

Such images need previous geometrical correction of existing distortions to ensure that the lines of text on the image are direct and horizontal. The existing ...

The proposed VD-based pre-processing model consists of five stages: a preparatory stage, page segmentation, thinning, baseline estimation, and slanting ...

We have analyzed the existing methods of correction of geometric distortions of text document images and reviewed the weaknesses of each method.

In this paper, we propose a simple yet efficient deep model named Adversarial Gated Unwarping Network (AGUN) to rectify these images.

A novel correction method for reducing perspective distortion in pipeline images was proposed for pipeline defect detection.

Nov 5, 2020 · B 0 and gradient distortion corrections significantly reduced the fallout (to 2.1% and 8.7%) and displacement (to 0.29 mm and 0.86 mm).

This research study the effect of resolution of raw images with respect to the reference images on the accuracy of geometric correction process, to finally get ...
