Context-based image recognition for consumer market research
First Claim
1. A method to determine whether a first image depicts a product, the method comprising:
- receiving the first image, the first image captured by a mobile device;
comparing, by executing an instruction with a processor, a first subset of feature points in a first region of interest of a reference image with a first subset of feature points of the first image residing within a first region corresponding spatially to the first region of interest and located at a first location in the first image to determine a first match value;
in response to determining the first match value satisfies a first threshold, comparing, by executing an instruction with the processor, a second subset of feature points in a second region of interest of the reference image with a second subset of the feature points of the first image residing within a second region of the first image corresponding spatially to the second region of interest to determine a second match value; and
in response to determining the second match value satisfies a second threshold lower than the first threshold, associating, by executing an instruction with the processor, the first image with product information associated with the reference image.

Abstract
Example methods, apparatus, systems to perform context-based image recognition for consumer market research are disclosed. Disclosed example methods include comparing a first subset of feature points in a first region of interest of a reference image with a first subset of feature points of a first image residing within a first region corresponding spatially to the first region of interest and located at a first location in the first image to determine a first match value. Disclosed example methods also include, in response to determining the first match value satisfies a first threshold, comparing a second subset of feature points in a second region of interest of the reference image with a second subset of the feature points of the first image residing within a second region of the first image corresponding spatially to the second region of interest to determine a second match value.

9. An apparatus to determine whether a first digital image depicts a product, the apparatus comprising:
-
a feature point extractor to determine feature points in the first digital image; and a reference comparator to; compare a first subset of feature points in a first region of interest of a digital reference image with a first subset of the feature points of the first digital image residing within a first region corresponding spatially to the first region of interest and located at a first location in the first digital image to determine a first match value; in response to determining the first match value satisfies a first threshold, compare a second subset of feature points in a second region of interest of the digital reference image with a second subset of the feature points of the first digital image residing within a second region of the first digital image corresponding spatially to the second region of interest to determine a second match value; and in response to determining the second match value satisfies a second threshold lower than the first threshold, associate the first digital image with product information associated with the digital reference image, at least one of the feature point extractor or the reference comparator including hardware. - View Dependent Claims (10, 11, 12, 13, 14, 15)
