Feature interpolation

摘要

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.

主权项

1. A computer-implemented method comprising:
receiving an image; extracting a portion of features of the image from the image; quantizing the extracted features into visual words; and interpolating a remaining portion of features of the image using the visual words and spatial configurations of visual words generated from a collection of training images and stored in a spatial configuration database.
