All Han-based scripts (Chinese, Japanese, and Korean) possess similar visual characteristics. Hence system development<br />
for identification of Chinese, Japanese and Korean scripts from a single document page is quite challenging. It is noted<br />
that a Han-based document page might also have Roman script in them. A multi-script OCR system dealing with Chinese,<br />
Japanese, Korean, and Roman scripts, demands identification of scripts before execution of respective OCR modules. We<br />
propose a system to address this problem using directional features along with a Gaussian Kernel-based Support Vector<br />
Machine. We got promising results of 98.39% script identification accuracy at character level and 99.85% at block level,<br />
when no rejection was considered.<br />

Robust 1D Barcode Recognition on Mobile Devices<br />
Rocholl, Johann, Stuttgart Univ.<br />
Klenk, Sebastian, Stuttgart Univ.<br />
Heidemann, Gunther, Stuttgart Univ.<br />
In the following we will describe a novel method for decoding linear barcodes from blurry camera images. Our goal was<br />
to develop a algorithm that can be used on mobile devices to recognize product numbers from EAN or UPC barcodes.<br />

Fast Logo Detection and Recognition in Document Images<br />

The scientific significance of automatic logo detection and recognition is more and more growing because of the increasing<br />
requirements of intelligent document image analysis and retrieval. In this paper, we introduce a system architecture which<br />
is aiming at segmentation-free and layout-independent logo detection and recognition. Along with the unique logo feature<br />
design, a novel way to ensure the geometrical relationships among the features, and different optimizations in the recognition<br />
process, this system can achieve improvements concerning both the recognition performance and the running time.<br />
The experimental results on several sets of real-word documents demonstrate the effectiveness of our approach.<br />

Magnetic Resonance Imaging (MRI) provides various imaging modes to study the brain. We tested the benefits of joint<br />
analysis of multimodality MRI data using joint independent components analysis (jICA) in comparison to unimodality<br />
analyses. Specifically, we designed a jICA to decompose the joint distributions of multimodality MRI data across image<br />
voxels and subjects into independent components that explain joint variations between image modalities across subjects.<br />
We applied jICA to structural and perfusion-weighted MRI data from 12 patients diagnosed with behavioral variant front<br />
temporal dementia (bvFTD), a type of dementia, and 12 healthy elderly individuals. While unimodality analyses showed<br />
widespread brain atrophy and hypoperfusion in the patients, jICA further revealed links between atrophy and hypoperfusion<br />
