Simple and Efficient Text Localization for Compressed Image in Mobile Phone
2014
Extraction of the text
data present in images involves Text detection, Text localization, Text
tracking, Text extraction, Text Enhancement and Text Recognition. Due to its
inherent complexity, traditional text localization algorithms in natural
scenes, especially in multi-context scenes, are not implementable under low
computational resources architectures such as mobile phones. In this paper, we
proposed a simple method to automatically localize signboard texts within JPEG
mobile phone camera images. Taking into account the information provided by the
Discrete Cosine Transform (DCT) used by the JPEG compression format, we delimitate
the borders of the most important text
region. This system is simple, reliable, affordable, easily implementable, and
quick even working under
architectures with low computational resources.
