A Survey on Text Extraction from Images

Abstract

This is survey paper on text extraction from images. A large number of algorithms and methods are proposed to extract text from the given image. Extraction of this information involves text region detection, text localization, tracking, character extraction, enhancement, and recognition of the text from a given image. Variations in text may occur because of differences in size, style, orientation, alignment of text, and low image contrast, composite backgrounds make the problem during extraction of text. The purpose of this paper is to classify and review various text extraction algorithms, discuss working and performance evaluation, and finding a technique for getting maximum accuracy.
