Abstract
Official abstract text for this publication.
Systems and methods for generating a visual vocabulary build a plurality of visual words via unsupervised learning on set of features of a given type; decompose one or more visual words to a collection of lower-dimensional buckets; generate labeled image representations based on the collection of lower dimensional buckets and labeled images, wherein labels associated with an image are associated with a respective representation of the image; and iteratively select a sub-collection of buckets from the collection of lower-dimensional buckets based on the labeled image representations, wherein bucket selection during any iteration after an initial iteration is based at least in part on feedback from previously selected buckets.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for building a visual vocabulary, the method comprising: generating visual words based on a set of features, wherein the visual words are defined in a higher-dimensional space; projecting the visual words from the higher-dimensional space to a first lower-dimensional space, thereby producing projections of the visual words in the first lower-dimensional space; generating a first collection of buckets in the first lower-dimensional space based on…
