Query: Single Classifier-based Passive System for Source Printer Classification
  using Local Texture Features   An important aspect of examining printed documents for potential forgeries
and copyright infringement is the identification of source printer as it can be
helpful for ascertaining the leak and detecting forged documents. This paper
proposes a system for classification of source printer from scanned images of
printed documents using all the printed letters simultaneously. This system
uses local texture patterns based features and a single classifier for
classifying all the printed letters. Letters are extracted from scanned images
using connected component analysis followed by morphological filtering without
the need of using an OCR. Each letter is sub-divided into a flat region and an
edge region, and local tetra patterns are estimated separately for these two
regions. A strategically constructed pooling technique is used to extract the
final feature vectors. The proposed method has been tested on both a publicly
available dataset of 10 printers and a new dataset of 18 printers scanned at a
resolution of 600 dpi as well as 300 dpi printed in four different fonts. The
results indicate shape independence property in the proposed method as using a
single classifier it outperforms existing handcrafted feature-based methods and
needs much smaller number of training pages by using all the printed letters.
