Abstract
Abstract A method and apparatus for transferring original data which includes images, between two stations located a distance apart, without actual transmission of the image portion of the data. A library of images are provided at each of the stations. The image to be transferred is processed into a description of the image which allows the reproduction of the image at the receiving end of the transmission using the images contained in the image library in the receiving station.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
249 words
A method of transferring data including an original image between a first station and a second station, the method comprising the steps of: receiving the data in the first station; extracting the original image from the data at the first station; retrieving a first stored image and a second stored image from a first image library in the first station and a stored first image identifier associated with the first stored image and a stored second image identifier associated with the second stored image; comparing the first stored image with the original image, and comparing the second stored image with the original image, at the first station; determining which of the first and second stored images most closely resembles the original image; calculating attribute vectors representing a difference between the most closely resembled one of the first and second stored images and the original image, at the first station; sending the stored image identifier of the most closely resembled one of the first and second stored images along with the attribute vectors to the second station; retrieving one of a third stored image and a fourth stored image, the third stored image corresponding to the first stored image and the fourth stored image corresponding to the second stored image, from a second image library in the second station using the stored image identifier; and modifying the retrieved stored image based on the attribute vectors to produce a modified image corresponding substantially to the original image, at the second station.
Claim 2
Independent Claim
249 words
A method of transferring data including an original image between a first station and a second station, the method comprising the steps of: receiving the data in the first station; extracting the original image from the data at the first station; retrieving a first stored image and a second stored image from a first image library in the first station and a stored first image identifier associated with the first stored image and a stored second image identifier associated with the second stored image; comparing the first stored image with the original image, and comparing the second stored image with the original image, at the first station; determining which of the first and second stored images most closely resembles the original image; calculating attribute vectors representing a difference between the most closely resembled one of the first and second stored images and the original image, at the first station; sending the stored image identifier of the most closely resembled one of the first and second stored images along with the attribute vectors to the second station; retrieving one of a third stored image and a fourth stored image, the third stored image corresponding to the first stored image and the fourth stored image corresponding to the second stored image, from a second image library in the second station using the stored image identifier; and modifying the retrieved stored image based on the attribute vectors to produce a modified image corresponding substantially to the original image, at the second station.
Claim 3
Dependent Claim
27 words
A system according to claim 1, wherein the original image is separated into a plurality of objects irrespective of locations of the objects in the original image.
Claim 4
Dependent Claim
96 words
A system according to claim 2, wherein each object is compared with both the first and the second images so as to determine which of the first and second images most closely resembles each object, wherein corresponding attribute vectors and associated image identifiers are produced for the most closely resembled one of the first and second images, and wherein the corresponding attribute vectors and associated image identifier of the most closely resembled one of the first and second images are transmitted to the second station for the producing of the modified image at the second station.
Claim 5
Dependent Claim
71 words
A system according to claim 3, wherein the attribute vectors of the most closely resembled one of the first and second images correspond to vectors having values representing at least: i) an angular relationship between the original image and the most closely resembled one of the first and second images, and ii) a size relationship between the original image and the most closely resembled one of the first and second images.
Claim 6
Dependent Claim
50 words
A system according to claim 2, wherein the stored image identifier of the most closely resembled one of the first and second images is used at the second station as a memory address pointer to retrieve the corresponding one of the third and fourth images from the second image library.
Claim 7
Dependent Claim
141 words
A system according to claim 1, wherein the first image library further includes a fifth image and the second image library further includes a sixth image corresponding to the fifth image, wherein the extracting step extracts geometrical characteristics of the original image, wherein, prior to the step of retrieving of the first and second images from the first image library, a preprocessing step is performed to compare the geometrical characteristics of the original image with stored geometrical characteristics of each of the first, second and third images in order to retrieve only certain ones of the first, second and third images which have corresponding stored geometrical characteristics which closely resemble the geometrical characteristics of the original image, and wherein only the retrieved certain ones of the first, second and third images are compared with the original image in the comparing step.
Claim 8
Dependent Claim
41 words
A system according to claim 1, wherein the first and second images correspond to object data that are stored in the first image library at the first station prior to receiving any image data to be transferred to the second station.
Claim 9
Independent Claim
232 words
A system for reproducing an original image present at a first station at a second station, comprising: a first image library at the first station storing at least a first image and a second image, the first image having a first identifier and second image having a second identifier; a second image library at the second station storing at least a third image and a fourth image, the third image substantially corresponding to the first image, the fourth image substantially corresponding to the second image; a comparison unit at the first station for comparing the original image with the first image and the second image, for determining which of the first and second images most closely resembles the original image, and for producing attribute data including information representing a difference between the original image and the most closely resembled one of the first and second images; a transmitting unit for transmitting the associated identifier and the attribute data of the most closely resembled one of the first and second images to the second station; and an image modifying unit at the second station, wherein the image modifying unit retrieves the corresponding one of the third and fourth images from the second image library based on the associated identifier and modifies the retrieved image based on the image characteristic information transmitted from the first station to produce a recreation of the original image.
