Unfolder: Fast localization and image rectification of a document with a crease from folding in half
A. M. Ershov, D. V. Tropin, E. E. Limonova +2
Presentation of folded documents is not an uncommon case in modern society. Digitizing such documents by capturing them with a smartphone camera can be tricky since a crease can di…
Advanced Hough-based method for on-device document localization
D. V. Tropin, A. M. Ershov, D. P. Nikolaev +1
The demand for on-device document recognition systems increases in conjunction with the emergence of more strict privacy and security requirements. In such systems, there is no dat…
Fast Projective Image Rectification for Planar Objects with Manhattan Structure
Julia Shemiakina, Ivan Konovalenko, Daniil Tropin +1
This paper presents a method for metric rectification of planar objects that preserves angles and length ratios. An inner structure of an object is assumed to follow the laws of Ma…
Dynamic Programming Approach to Template-based OCR
M. A. Povolotskiy, D. V. Tropin
In this paper we propose a dynamic programming solution to the template-based recognition task in OCR case. We formulate a problem of optimal position search for complex objects co…
