Abstract: Digital image processing of a low resolution source image to produce a high resolution result image may be accomplished by partitioning the low resolution source image into a plurality of low resolution image parts; for each low resolution image part, comparing the low resolution image part to low resolution reference images to determine at least one most similar low resolution reference image; determining if the most similar low resolution reference images are related to one another; and constructing a high resolution result image based at least in part on high resolution images corresponding to related most similar low resolution reference images.

Abstract: Methods of radiofrequency identification and analysis are disclosed. In one aspect, a method may include transmitting a wireless interrogation signal. Corresponding wireless response signals may be received from each of a plurality of transponders. Then, analysis of interrelationships between different types of objects each associated with one of the transponders may be performed. Software and apparatus to perform such methods are also disclosed. In another aspect, a method of radiofrequency identification may include accessing additional information about one or more objects that are each associated with a different one of the transponders from a peripheral database.
