Abstract: An interactive device, such as a toy, equipped with an image similarity engine capable of receiving external visual inputs and providing corresponding physical outputs. The device captures an image, compares the captured image with images stored in a database, and provides physical outputs according to the recognized images.

Abstract: An apparatus, method and computer program for recognizing one or more images within digitized image data that might include a target image desired to be located. The system generates a set of domain blocks from the image data where each domain block represents a discrete portion the image data and a set of range blocks from one or more target images. Either the domain blocks, the range blocks, or both, are transformed by one or more substantially affine transformations with predetermined coefficients to create possible variants of the images. A comparison between the blocks is made to determine similarity, and includes at least a measurement of whether better matching is achieved when a range block is chosen from image data representing the image which is the source of the domain block or when chosen from other image data.

Abstract: A system and method for compressing and decompressing datastreams with fractal coding is disclosed. The method includes the generation of an optimal data set transformation function corresponding to a representative datastream captured from a data source. The data set transformation function is determined by ordering the digits of the representative datastream to order the intervals of an attractor. The ordered intervals are then used to determine the mapping functions which define an optimal data set transformation function. The nodes or graphical representation of the data set transformation function are incorporated in a compressor/decompressor combination. The compressor receives data symbols from a data source and determines the next interval of an attractor using a composition operation. The address or a portion of the address is shifted out as a number representative of the data symbols. Preferably, the interval is renormalized so the interval may be represented in sixteen bits.
