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…
MIDV-2020: A Comprehensive Benchmark Dataset for Identity Document Analysis
Konstantin Bulatov, Ekaterina Emelianova, Daniil Tropin +8
Identity documents recognition is an important sub-field of document analysis, which deals with tasks of robust document detection, type identification, text fields recognition, as…
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…
Approach for Document Detection by Contours and Contrasts
Daniil V. Tropin, Sergey A. Ilyuhin, Dmitry P. Nikolaev +1
This paper considers arbitrary document detection performed on a mobile device. The classical contour-based approach often fails in cases featuring occlusion, complex background, o…
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…
