Is Computer Vision Pattern Recognition by a Different Name?

Dept. of Computer Science (March 26, 2015)

SEMINAR SERIES : Distinguished lecture

MAJOR SPEAKER : Chellappa, Rama
LENGTH : 67 min.
ACCESS : Open to all
SUMMARY : As someone who has been working in computer vision and pattern recognition for over three decades, I have watched with interest how most existing efforts in computer vision are based on pattern recognition methodologies. More and more, the algorithms take the form, data (image, video, depth, etc.), features (SIFT, Hog, LBB, attributes, dictionaries, etc.) followed by a favorite version of SVMs. This approach has generated successful algorithms such as deformable parts model for object detection, attribute-based face verification, etc. More recently, a different manifestation of pattern recognition algorithms, based on deep learning has produced best results on ImageNet and LFW data sets. While I am a devoted student of pattern recognition school from Purdue, I would like to argue that domain shifts due to illumination and pose variations, blur and resolution as well as occlusion will require the incorporation of models and geometry to realize generalizations across data and help design robust systems. I call for a balanced approach that effectively combines imaging and geometric models and data for reaping long term gains.  [Go to the full record in the library's catalogue]
