STEFANN: Scene Text Editor using Font Adaptive Neural Network
Textual information in a captured scene plays an important role in scene
interpretation and decision making. Though there exist methods that can
successfully detect and interpret complex text regions present in a scene, to
the best of our knowledge, there is no significant prior work that aims to
modify the textual information in an image. The ability to edit text directly
on images has several advantages including error correction, text restoration
and image reusability. In this paper, we propose a method to modify text in an
image at character-level. We approach the problem in two stages. At first, the
unobserved character (target) is generated from an observed character (source)
being modified. We propose two different neural network architectures - (a)
FANnet to achieve structural consistency with source font and (b) Colornet to
preserve source color. Next, we replace the source character with the generated
character maintaining both geometric and visual consistency with neighboring
characters. Our method works as a unified platform for modifying text in
images. We present the effectiveness of our method on COCO-Text and ICDAR
datasets both qualitatively and quantitatively.Comment: Accepted in The IEEE Conference on Computer Vision and Pattern

is a difficult task because of complex character shapes
due to the presence of modified/compound characters
as well as zone-wise writing styles of different individuals.
Most of the research published so far on Bengali
handwriting recognition deals with either isolated
character recognition or isolated word recognition,
and just a few papers have researched on recognition
of continuous handwritten Bengali. In this paper
we present a research on continuous handwritten
Bengali. We follow a classical line-based recognition
approach with a system based on hidden Markov
models and n-gram language models. These models
are trained with automatic methods from annotated
data. We research both on the maximum likelihood
approach and the minimum error phone approach for
training the optical models. We also research on the
use of word-based language models and characterbased
language models. This last approach allow us
to deal with the out-of-vocabulary word problem in
the test when the training set is of limited size. From
the experiments we obtained encouraging results.This work has been partially supported through the European Union’s H2020 grant READ (Recognition and Enrichment of Archival Documents) (Ref: 674943) and partially supported by MINECO/FEDER, UE under project TIN2015-70924-C2-1-R.Sánchez Peiró, JA.; Pal, U.
