BACKGROUND

This disclosure relates generally to image processing. More particularly, but not by way of limitation, this disclosure relates to techniques and systems for utilizing an appearance transform network to generate data for descriptor learning.

Computer vision often relies upon identification of keypoints in an image, from which feature descriptors can be determined to obtain information in a scene. Typically, feature descriptors may be determined using a descriptor network which has been trained to identify feature descriptors from reference images. For example, images may be captured of a scene during different times or while the scene has different characteristics. Those images may then be utilized to identify keypoints, which may be utilized for detection, image retrieval, localization, and the like.
