Abstract:
A frequent challenge for many Text Understanding Systems is to
tackle the variety of text characteristics in born-digital and natural
scene images to which current OCRs are not well adapted. For
example, texts in perspective are frequently present in real-word
images, but despite the ability of some detectors to accurately
localize such text objects, the recognition stage fails most of the
time. Indeed, most OCRs are not designed to handle text strings
in perspective but rather expect horizontal texts in a parallel-frontal
plane to provide a correct transcription. In this paper, we propose a
rectification procedure that can correct highly distorted texts, subject
to rotation, shearing and perspective deformations. The method is
based on an accurate estimation of the quadrangle bounding the
deformed text in order to compute a homography to transform this
quadrangle (and its content) into a horizontal rectangle.
The rectification is validated on the dataset proposed during the
ICDAR 2015 Competition on Scene Text Rectification.
