Patent Images
1. A computer-implemented method comprising:
- receiving a collection of training images;
extracting features from the collection of training images;
quantizing the extracted features into visual words;
determining spatial configurations of the visual words in the training images;
storing the spatial configurations of the visual words in a spatial configuration database; and
extracting a portion of features of an image and utilizing the spatial configurations of the visual words stored in the spatial configuration database to interpolate a remaining portion of features of the image.

Abstract
Feature interpolation techniques are described. In a training stage, features are extracted from a collection of training images and quantized into visual words. Spatial configurations of the visual words in the training images are determined and stored in a spatial configuration database. In an object detection stage, a portion of features of an image are extracted from the image and quantized into visual words. Then, a remaining portion of the features of the image are interpolated using the visual words and the spatial configurations of visual words stored in the spatial configuration database.
