Abstract
A method and system for processing images for a search is provided, including: receiving a plurality of images selected from search results; for each image in the plurality of images, retrieving a feature vector associated with the image; selecting a subset of the feature vectors based on similarity of feature vectors associated with the images in the plurality of images; and performing a search for feature vectors in a database similar to the feature vectors in the subset of feature vectors.
Claims19
A method of processing images for a search, comprising:
- receiving a plurality of images selected from search results;
- for each image in the plurality of images, retrieving a respective feature vector associated therewith;
- selecting a subset of the feature vectors based on similarity of the feature vectors;
- and
- performing a search for feature vectors in a database similar to feature vectors in the subset of feature vectors, and
- wherein the plurality of images come from video captured by a camera.
A method of processing images for a search, comprising:
- conducting a search for images similar to a reference image;
- receiving a plurality of images selected from search results;
- for each image in the plurality of images, retrieving a respective feature vector associated therewith;
- selecting a subset of the feature vectors based on similarity of the feature vectors;
- locating feature vectors in a database similar to feature vectors in the subset of feature vectors;
- and
- displaying images associated with the located feature vectors.
