6970579 Orientation invariant feature detection system and method for unstructured low-quality video  
A system and method for detecting features in video from business meetings and video teleconferencing systems can use color, motion, morphological (shape) filtering and a set of heuristic rules to...
6865291 Method apparatus and system for compressing data that wavelet decomposes by color plane and then divides by magnitude range non-dc terms between a scalar quantizer and a vector quantizer  
An apparatus and method for image data compression performs a modified zero-tree coding on a range of image bit plane values from the largest to a defined smaller value, and a vector quantizer...
5539663 Process, apparatus and system for encoding and decoding video signals using temporal filtering  
For decoding, a first portion of an encoded bitstream is decoded to generate a first decoded video frame. A second portion of the encoded bitstream is decoded to generate a second decoded video...
5394190 Video signal encoding apparatus  
A field to be encoded is divided into blocks. Then, first, second, and third motion vectors relative to data of a block of the field to be encoded are calculated from data of an m-th preceding...
4774574 Adaptive block transform image coding method and apparatus  
In a method and apparatus for transmitting a digital image over a limited bandwidth communication channel, an image is block transformed to produce blocks of transform coefficients; the transform...
4504860 Method and process for transmitting an image  
A method and an apparatus for transmitting an image in which the image is sampled at a first plurality of points. The samples are then subjected to a two-dimensional unitary transform to produce a...
