Abstract
Various embodiments may obtain an image representation of an object for use in image matching and content retrieval. For example, an image matching system processes video content items to determine one or more scenes for one or more video content items. The image matching system can extract, from at least one video frame for a scene, feature descriptors relating to one or more objects represented in the at least one video frame. The image matching system indexes the feature descriptors into a feature index storing information for each of the feature descriptors and respective corresponding video frame. The image matching system correlates the feature descriptors of the feature index to determine one or more groups having similar feature descriptors. The image matching system indexes the one or more groups into a correlation index storing information for each of the one or more groups and respective corresponding feature descriptors.
