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.

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

  • COPDChronic Obstructive Pulmonary Disease

  • CHFCongestive Heart Failure

  • D/SDextrose in Saline

  • PIDPelvic Inflammatory Disease

  • GSWGunshot Wound

  • NKANo known allergies

  • KVOKeep vein open

  • NaCLSodium Chloride

  • PhD Student: Robert Milewski


    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


    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.

    II. Fingerprint Analysis and Recognition

    PhD Students: Tsai-yang Jea, Chaohong Wu


    Partial matching

    ?

    Latent partial fingerprints


    III Hand Geometry

    Hand geometry biometrics

    and fingerprints


    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


    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
