Text Detection and Recognition in Imagery: A Survey

TLDR
This review provides a fundamental comparison and analysis of the remaining problems in the field and summarizes the fundamental problems and enumerates factors that should be considered when addressing these problems.
Abstract
This paper analyzes, compares, and contrasts technical challenges, methods, and the performance of text detection and recognition research in color imagery It summarizes the fundamental problems and enumerates factors that should be considered when addressing these problems Existing techniques are categorized as either stepwise or integrated and sub-problems are highlighted including text localization, verification, segmentation and recognition Special issues associated with the enhancement of degraded text and the processing of video text, multi-oriented, perspectively distorted and multilingual text are also addressed The categories and sub-categories of text are illustrated, benchmark datasets are enumerated, and the performance of the most representative approaches is compared This review provides a fundamental comparison and analysis of the remaining problems in the field

Limits on super-resolution and how to break them

TL;DR: This work derives a sequence of analytical results which show that the reconstruction constraints provide less and less useful information as the magnification factor increases, and proposes a super-resolution algorithm which attempts to recognize local features in the low-resolution images and then enhances their resolution in an appropriate manner.
