  1. Moving Cast Shadow Detection using Physics-based Features Jia-Bin Huang Chu-Song Chen Taiwan , Taipei CVPR 2009

  2. Outline • Introduction • Algorithm • Learning • Detection • Experiment • Conclusion

  3. Introduction

  4. Algorithm

  5. Bi-illuminant Dichromatic Reflection Model ( BIDR ) • Consider only matte surfaces • The camera sensor response (spectral projection )

  6. Gradient Intensity Distortion

  7. Learning

  8. Detection

  9. Experiment

  10. Conclusion • A global shadow model learned from physics-based features • Does not require numerous foreground activities or high frame rates to learn the shadow model parameters • Can be used for fast learning of local features in pixel-based models
