Proceedings ArticleDOI
Representing shape with a spatial pyramid kernel
TL;DR: This work introduces a descriptor that represents local image shape and its spatial layout, together with a spatial pyramid kernel that is designed so that the shape correspondence between two images can be measured by the distance between their descriptors using the kernel.
Proceedings ArticleDOI
Image Classification using Random Forests and Ferns
TL;DR: It is shown that selecting the ROI adds about 5% to the performance and, together with the other improvements, the result is about a 10% improvement over the state of the art for Caltech-256.
Book ChapterDOI
Scene classification via pLSA
TL;DR: The classification performance under changes in the visual vocabulary and number of latent topics learnt is investigated, and a novel vocabulary using colour SIFT descriptors is developed using probabilistic Latent Semantic Analysis.
Journal ArticleDOI
Scene Classification Using a Hybrid Generative/Discriminative Approach
TL;DR: This work introduces a novel vocabulary using dense color SIFT descriptors and investigates the classification performance under changes in the size of the visual vocabulary, the number of latent topics learned, and the type of discriminative classifier used (k-nearest neighbor or SVM).
Journal ArticleDOI
Review: Which is the best way to organize/classify images by content?
Anna Bosch,X. Munoz,Robert Martí +2 more
TL;DR: A detailed review of some of the most commonly used scene classification approaches, giving the advantages and disadvantages of each methodology.
