tailieunhanh - Beyond bags of features: Adding spatial information

Invite you to consult the lecture content "Beyond bags of features: Adding spatial information" below. Contents of lectures introduce to you the content: Implicit shape models, probabilistic model, results motorbikes and airplanes,. Hopefully document content to meet the needs of learning, work effectively. | Beyond bags of features: Adding spatial information Many slides adapted from Fei-Fei Li, Rob Fergus, and Antonio Torralba Adding spatial information Computing bags of features on sub-windows of the whole image Using codebooks to vote for object position Generative part-based models Spatial pyramid representation Extension of a bag of features Locally orderless representation at several levels of resolution level 0 Lazebnik, Schmid & Ponce (CVPR 2006) Spatial pyramid representation Extension of a bag of features Locally orderless representation at several levels of resolution level 0 level 1 Lazebnik, Schmid & Ponce (CVPR 2006) Spatial pyramid representation level 0 level 1 level 2 Extension of a bag of features Locally orderless representation at several levels of resolution Lazebnik, Schmid & Ponce (CVPR 2006) Scene category dataset Multi-class classification results (100 training images per class) Caltech101 dataset Multi-class classification results (30 training images per class) Implicit shape models Visual codebook is used to index votes for object position B.
