  • Optical Character Recognition - a Combined ANN/HMM Approach
    Optical Character Recognition - A Combined ANN/HMM Approach Dissertation submitted to the Department of Computer Science Technical University of Kaiserslautern for the fulfillment of the requirements for the doctoral degree Doctor of Engineering (Dr.-Ing.) by Sheikh Faisal Rashid Dean: Prof. Dr. Klaus Schneider Thesis supervisors: Prof. Dr. Thomas Breuel, TU Kaiserslautern Prof. Dr. Andreas Dengel, TU Kaiserslautern Chair of supervisory committee: Prof. Dr. Karsten Berns, TU Kaiserslautern Kaiserslautern, 11 July, 2014 D 386 Abstract Optical character recognition (OCR) of machine printed text is ubiquitously considered as a solved problem. However, error free OCR of degraded (broken and merged) and noisy text is still challenging for modern OCR systems. OCR of degraded text with high accuracy is very important due to many applications in business, industry and large scale document digitization projects. This thesis presents a new OCR method for degraded text recognition by introducing a combined ANN/HMM OCR approach. The approach provides significantly better performance in comparison with state-of-the-art HMM based OCR methods and existing open source OCR systems. In addition, the thesis introduces novel applications of ANNs and HMMs for document image preprocessing and recognition of low resolution text. Furthermore, the thesis provides psychophysical experiments to determine the effect of letter permutation in visual word recognition of Latin and Cursive script languages. HMMs and ANNs are widely employed pattern recognition paradigms and have been used in numerous pattern classification problems. This work presents a simple and novel method for combining the HMMs and ANNs in application to segmentation free OCR of degraded text. HMMs and ANNs are powerful pattern recognition strategies and their combination is interesting to improve current state-of-the-art research in OCR.

Far from being an obsolete skill, more and more people today are picking up the pen and creating their own greeting cards, wedding invitations, fine art projects, and even creating their own computer fonts! In the old days, calligraphy tools were unique and specically crafted to their task. Today, a calligrapher has a wide variety of tools from which to choose, from traditional to completely modern, even digital! Calligraphers can now experiment with their artistic expression, freely mixing creative ideas and elements together to explore new artforms with their projects. In this book we’ll examine the basic techniques of calligraphy, covering calligraphy hands suitable for a wide variety of projects and easy for a beginner or intermediate calligrapher to practice and learn. We’ll also cover easy decorative techniques such as watercolor painting, Celtic knotwork, gold leang and illustration ideas to create a “toolkit” of creative techniques.

It offers a mechanism to compare a string against a baselined copy and update the baselined copy to match the new value when a mismatch occurs. The update process includes a manual step to facilitate a review of the change before acceptance. The tool uses multi-line string format for string baselines to improve readability for human review. Contents 1 baseline Documentation, Release 1.2.1 2 Contents CHAPTER 1 Quick Start Create an empty baseline with a triple quoted multi-line string. Place the ending triple quote on a separate line and indent it to the level you wish the string baseline update to be indented to. Add a compare of the string being tested to the baseline string. Then save the file as fox.py: from baseline import Baseline expected= Baseline(""" """) test_string= """THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG.""" assert test_string == expected Run fox.py and observe that the assert raises an exception since the strings are not equal. Because the comparison failed, the tool located the triple quoted baseline string in the source file and updated it with the mis-compared value. When the interpreter exited, the tool saved the updated source file but changed the file name to fox.py.update: from baseline import Baseline expected= Baseline(""" THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG.

  • Font Features for Andika
    Font Features for Andika When Andika is used in applications that support Graphite, and that provide an appropriate user interface, various user-controllable font features are available that allow access to alternatively-designed glyphs that might be preferable for use in some contexts. In LibreOffice 3.4.2+ (http://www.libreoffice.org/download/) or OpenOffice 3.2+ (http://www.openoffice.org/download/) the font features can be turned on by choosing the font (ie Andika), followed by a colon, followed by the feature ID, and then followed by the feature setting. So, for example, if the Uppercase eng alternate “Capital N with tail” is desired, the font selection would be “Andika:Engs=2”. (The Graphite feature IDs have changed. If you already have documents which specify the Graphite feature IDs as digits, you will need to change from digits to text. Both are documented in the table below. We are very sorry for the inconvenience.) If you wish to apply two (or more) features, you can separate them with an “&”. Thus, “Andika:Engs=2&smcp=1” would apply “Capital N with tail” plus the “Small capitals” feature. These same features are also available in OpenType. The OpenType feature IDs (“cvxx” for “Character Variant” and “ssxx” for “Stylistic Set”) are listed in the OpenType feature ID column. However, they are only available in a few applications. Mozilla Firefox (https://www.mozilla.org/firefox) is the only application that currently supports Character Variants. Adobe InDesign, Microsoft Word, Microsoft Publisher and Mozilla Firefox support Stylistic Sets. A glyph palette is available for accessing the alternate glyphs in some applications such as Adobe InDesign.
