Application ID: 14042558

Base Claim:
1. A method comprising: generating, by a device, a hierarchically arranged data structure to be used when classifying one or more objects included within a query image based on multi-resolution query feature descriptor extracted from the query image at a first scale space resolution and a second scale space resolution, wherein the hierarchically arranged data structure represents a first query feature descriptor of the multi-resolution feature descriptor extracted at the first scale space resolution and a second corresponding query feature descriptor of the multi-resolution feature descriptor extracted at the second scale space resolution hierarchically arranged according to the first scale space resolution and the second scale space resolution; and performing, by the device, a visual search based on the generated data structure.

Claim 2:
2. The method of claim 1 , wherein the first feature descriptor is extracted from a patch of the query image, the patch being processed at the first scale space resolution prior to extracting the first feature descriptor, and wherein the second feature descriptor is extracted from the patch of the query image, the patch being processed at the second scale space resolution prior to extracting the second feature descriptor.
