Methods to process digital video using trajectory extraction and spatiotemporal decomposition for search and retrieval of video are described. An example method extracts interest point data from data representing a plurality of video frames. The interest point data is extracted from each of the video frames independent of the other video frames. Subsequent to extracting the interest point data, the example method links at least some of the interest point data to generate corresponding trajectory information. The example method also clusters the trajectory information to form clustered trajectory information and extracts a representative feature index from the clustered trajectory information.
