Improving the Print Quality of Screenshots

摘要

This article considers a method of improving print quality for screenshots. The proposed method is based on detecting and vectorizing text areas on raster images. The main study is dedicated to smooth screen-text segmentation, determining background and text color, improving resolution, and recovering the contour of symbols and approximating them with Bezier curves. The proposed method is resistant to different colors, text sizes, and languages and makes it possible to obtain a sharp and correct text display for printing.
