We propose a signature scheme for identifying a related class of images based upon the content of the images. With the proposed scheme, we represent an image to a collection of rules based upon a technique using relationships derived from the pixels of images. This collection of relationships or rules is called Finite Inductive sequences. These rules make(More)

This assumption clearly overlooks the common scenario that sensor nodes are usually duty-cycled in order to save energy. In this paper we propose a kind of novel DV(More)
