Abstract
A method for generating an image representation includes generating a set of embedded descriptors, comprising, for each of a set of patches of an image, extracting a patch descriptor which is representative of the pixels in the patch and embedding the patch descriptor in a multidimensional space to form an embedded descriptor. An image representation is generated by aggregating the set of embedded descriptors. In the aggregation, each descriptor is weighted with a respective weight in a set of weights, the set of weights being computed based on the patch descriptors for the image. Information based on the image representation is output. At least one of the extracting of the patch descriptors, embedding the patch descriptors, and generating the image representation is performed with a computer processor.
