Abstract: Methods, systems, devices, and implementing technologies for up-scaling an original source video from a lower, first resolution to a desired output video having a higher, second resolution, using fractal zooming techniques to replace individual source pixels in each respective image frame of the original source video with a plurality of proposed replacement pixels in the vertical and horizontal dimensions having similar characteristics as the individual source pixel, reducing noise associated with each respective frame of the desired output video, re-sizing, as necessary, each respective replacement frame to the second resolution, and outputting each zoomed replacement frame to generate the desired output video, which is an up-scaled version of the original source video. The quality of the up-scaled output video is improved by using artifact filtering and linear smoothing techniques after the initial search and replace steps of the fractal zooming process.

The fractal zooming techniques include identifying a plurality of candidate pixels from the source video and selecting a group of pixels from the candidate pixels that best matches the individual source pixel.

Abstract: A system and method is disclosed for representing each frame in a sequence of video frames in terms of a correlation between successive video frames. The system and method of the present invention segment the current video frame data and a previous frame into blocks for which motion vectors and/or affine mapping coefficients may be determined. The motion vectors may then be used to represent the current frame data without requiring periodic transmission of a base, self-referential frames of video data. Preferably, the compressor which generates the codewords to represent the current frame data subdivides the blocks of the current frame and previous frame buffers to further evaluate motion factors which may be used to represent current frame data. This evaluation is performed in a recursive manner and preferably includes evaluation of a bit rate/distortion factor to optimally select codewords for representing the current frame data.

Abstract: A method and apparatus are described for-encoding a three-dimensional array of data representing a physical entity, such as an image (or sequence of frames), by means of its local symmetries. This encoding yields both compression and a resolution-independent description which allows reconstruction of the image to an arbitrary scale. Spatial zooming and interframe interpolation can be achieved without significant loss of information.

Abstract: A system and method for contractively mapping decompressed images to facilitate resynchronization of data transmission is provided. This system includes a transmitter having a data compressor, a decompressor, and a contractive mapper. The receiver for the data transmission includes a decompressor and contractive mapper. The decompressor and contractive mapper of the transmitter provide the compressor with the same information which the decompressor at the receiver is using to decompress data. In this manner, the compressor may accurately represent the incoming frame data in terms of the contractively mapped decompressed data. The contractive mapper attenuates information in the decompressed data frame to prevent the persistence of erroneous data at the receiver should data become corrupted during transmission or the transmission be interrupted. The contractive mapping is preferably achieved with an affine map contracting scheme which is preferably implemented by a scalar multiplication.
