Text detection in images is an important component for a wide range of applications. The most obvious one is Optical Character Recognition (OCR). It can be used to digitize the content of paper documents, to automate the annotation and indexing of multimedia documents, to provide computerized aid for visually impaired, and for many other purposes. Common OCR tools being designed to detect and recognize paragraphs of text perform well on scanned documents, but fail to recognize text in drawings, charts and images of natural scenes when applied to the whole image. Other algorithms for text detection are required for these types of images. This talk will address key approaches to a problem of text detection for various types of images and showcase text detection for charts and screenshots. We will discuss script dependency of the approaches under study: which of them are capable of performing equally well for Latin, Cyrillic or Chinese?
