  1. Pattern Analysis and Machine Intelligence Applications Venu Govindaraju Dept. of Computer Science & Engineering University at Buffalo govind@cse.buffalo.edu

  2. Research Projects • Document Image Analysis and Recognition • Interactive Recognition NSF: 2003-04 • Digital Libraries NSF: 2002-04 • Public Health Surveillance NSF: 2003-04 • Unified Biometrics and Sensors • Biometric Systems NYSTAR: 2003-0 • Fingerprint Recognition Ultra-Scan Inc: 2002-04 • Hand Geometry Infinite Group Inc : 2003-04 • Cancelable BiometricsCUBRC: 2003-04 • Patho-biometrics AFMIC: 2003-04

  3. Document Analysis and Recognition Goal: Everything that can be done with symbolically encoded datacan also be done with scanned hardcopy documents.   Searching document images, presenting them legibly,navigating within and among them.

  4. I Interactive Recognition Models Ranked Lexicon Context PhD Student: Vemulapati Ramanaprasad

  5. I Interactive Recognition Models Ranked Lexicon Context

  6. Grapheme Models

  7. Structural Features, BAG End Loops Junction End Loop Turns

  8. Continuous Attributes

  9. II Multilingual Digital Libraries • South Asian Languages • Hindi (Devanagari script), Urdu (Arabic Script), Telugu • Covers a billion people! • Script discrimination • Multilingual querying PhD Students: Faisal Farooq, Surya Kompalli

  10. Digital Library application Document Truth Grayscale Images Manual Truthing Multi-lingual Query Panel english OCR design Semi-Automatic Annotation Script Analysis Multilingual Digital Archives

  11. II Public Health Surveillance Thousands are filed a day. Passed from EMS to Hospital. PCR Purpose: • Medical care/diagnosis • Legal Documentation • Quality Assurance • EMS Abbreviations • COPD Chronic Obstructive Pulmonary Disease • CHF Congestive Heart Failure • D/S Dextrose in Saline • PID Pelvic Inflammatory Disease • GSW Gunshot Wound • NKA No known allergies • KVO Keep vein open • NaCL Sodium Chloride PhD Student: Robert Milewski

  12. Medical Text Recognition and Data Mining Check box recognition, Numeral recognition Large lexicons, partial recognition, abbreviations ChronicObstructive PulmonaryDisease”: CRC-OBV-UOARY-DISAE Contextual knowledge, constraints and lexicon reduction

  13. Unified Biometrics and Sensors Biometrics are automated methods of identifying a person or verifying the identity of a person based on a physiological or behavioral characteristic.

  14. I UB STARS: Unobtrusive Biometric Sense Transmit Assess and Respond Systems Biometrics (Pattern Recognition & Analysis) Govindaraju Light Sources (Materials Development & Characterization) Analog VLSI (Smart Systems) Packaged Device Cartwright (EE) Titus (EE) Sensors (Materials Development) Bright (Chem) Cartwright &

  15. II. Fingerprint Analysis and Recognition PhD Students: Tsai-yang Jea, Chaohong Wu

  16. Partial matching ? Latent partial fingerprints

  17. III Hand Geometry Hand geometry biometrics and fingerprints

  18. IV Cancelable Biometrics • Intentional, repeatable distortion of biometric signal based on a chosen transform • One-way non-invertible mapping using another biometric data giving layered security • Transform minutiae points on fingerprints using signature features PhD Student: Sergey Tulyakov

  19. V Animal Biometrics Visible Symptoms of FMD • Straying from the herd • Swaying gait, sometimes with high stepping of the feet • Difficulties in walking or getting up • Loss of weight, milk yield

  20. Original image Animals Empty field Texture Analysis

  21. Other Projects • Signature Verification • HanSheng Lei (PhD) Srinivas Palla (MS) • Devanagari OCR • Swapnil Khedekar (MS) • Biometric Data Representation • Viraj Chavan (MS) • Web Security and CAPTCHA • Sumit Manocha (MS) • Video HWR • Sijun Kung (PhD)
