Abstract:
A system and method for information retrieval comprises a computing device with a client and a progressive feature server coupled by a network. The client includes a feature extraction module, a progressive sending module, a sampling module and a feedback receiver. The progressive sending module divides the features into groups and sends them to the server. The progressive sending module is also responsive to commands from the feedback receiver to terminate the transmission of additional features if a match is found. The progressive feature server is coupled for communication with the client and includes a progressive receiving module, a feedback generator, an image recognizer and a result delivery module. The image recognizer progressively processes the groups of extracted features received from the client and provides results and hints for improved recognition. The present invention also includes methods for processing captured information progressively, sending extracted features in groups, and progressively performing image recognition for improved recognition speed.
