Text Detection and Localization in Low Quality Video Images through Image Resolution Enhancement Technique

Abstract

Video text information plays an important role in semanticbased video analysis, indexing, and retrieval. Text embedded in the image or video contains very useful information like the name of the person, title, location and sometimes brief description of the image. Many algorithms have been proposed to detect and localize the text information present in video images. In this paper, we proposed a methodology to enhance the quality of the image and then detect and localize text regions from low quality video images. Experimental results show the proposed method achieves improved precision rate and recall rate.

Secured platform for healthcare data: privacy preservation based blockchain environment

“…Even though there are many technical processes to maintain the security constraints, the user’s privacy is a great challenge for researchers. Meanwhile, the use of optimization logic (Swamy et al , 2013; Tiago et al , 2020; Kumar et al , 2019; Anand, 2021; Kumar et al , 2021; Kumar et al , 2012) brings more advantageous outcomes that the researchers did not expect.…”
