Transcript

  • 1. Face detection
    Tuck N.
  • 2. IDEF0 decomposition
  • 3. Face detection’s approaches
    Contour images analysis
    Intensity and colors analisys
    Adaptive classifier
  • 4. Contour images analysis
  • 5. Face detection’s approaches
  • 6. Face detection’s approaches
    Skin color’s cluster
  • 7. Adaptive classifier
  • 8. Adaptive classifier
  • 9. AdaBoost
    AdaBoost is an algorithm for constructing a “strong” classifier as linear combination
    f(x) =αtht(x)
    of “simple” “weak” classifiers ht(x) : X -> {−1,+1}.
  • 10. Rapid Object Detection using a Boosted Cascade of Simple Features
    Integral Images
  • 11. Algorithm workflow
  • 12. Classifier’s algorithm workflow
  • 13. OWL model
    We can use OWL model to store some data, used in our application. For example, I’ve stored maximum and minimum area of faces, that should be detected. According to w3c standarts:
    <owl:Restriction>
    <owl:onPropertyrdf:resource="#minWidth" />
    <owl:minCardinalityrdf:datatype="&xsd;nonNegativeInteger">20</owl:minCardinality>
    </owl:Restriction>
    <owl:Restriction>
    <owl:onPropertyrdf:resource="#maxWidth" />
    <owl:maxCardinalityrdf:datatype="&xsd;nonNegativeInteger">300</owl:maxCardinality>
    </owl:Restriction>
  • 14. OWL and C# interaction
    We can use standartXmlDocumentReader to parse OWL model. Also we can use LINQ to parse this model.
