Color Attributes for Object Detection CVPR 2012 Poster
Outline • Introduction • Color attributes for object detection • Coloring object detection • Cartoon character detection • Experiment • Conclusion
Introduction • Why with color attributes? • There are few approach apply color for object detection on a single class. [15] W. R. Schwartz, A. Kembhavi, D. Harwood, and L. S. Davis. Human detection using partial least squares analysis. In ICCV, 2009. [22] S. Walk, N. Majer, K. Schindler, and B. Schiele. New features and insights for pedestrian detection. In CVPR, 2010. [2] R. M. Anwer, D. Vazquez, and A. M. Lopez. Color contribution to part-based person detection in different types of scenarios.
Introduction • Feature combination: Early fusion
Introduction • Feature combination: Late fusion
Introduction • Photometric invariance • provides guidelines on how to ensure invariance with respect to such event • Compactness
Color attributes for object detection • Color descriptor • Robust hue descriptor(HUE): • Opponent derivative descriptor(OPP):
Color attributes for object detection • Color descriptor • Color names(CN):
Color attributes for object detection • Color descriptor evaluation
Coloring object detection • Coloring part-based object detection
Coloring object detection • Coloring efficient subwindow search • Based on a bag-of-words representation of the image.
Cartoon character detection • New dataset: 586 images , 18 categories
Experiment • On the PASCAL VOC datasets • Coloring part-based object detection
Experiment • On the PASCAL VOC 2009
Experiment • On the PASCAL VOC datasets • Coloring ESS-based object detection • Provide good localization results on cat and dog of the PASCAL VOC 2007. • Cat: 20.7%->22.3% • Dog: 13.8%->15.8%
Experiment • On the PASCAL VOC datasets • Comparison with state-of-the-art results
Experiment • On the cartoon dataset • Coloring part-based object detection
Experiment • On the cartoon dataset • Coloring ESS-based object detection
Conclusion • Know that the difference of two feature combination. • Realize that the problem of incorporating color for object detection.
