Abstract: A compression and decompression system in which a reversible wavelet filter are used to generates coefficients from input data, such as image data. The reversible wavelet filter is an efficient transform implemented with integer arithmetic that has exact reconstruction. The present invention uses the reversible wavelet filter in a lossless system (or lossy system) in which an embedded codestream is generated from the coefficients produced by the filter. An entropy coder performs entropy coding on the embedded codestream to produce the compressed data stream.

Abstract: A method and apparatus for storing bitplanes of coefficients in a reduced size memory is disclosed. In one embodiment, a method for encoding coefficients comprises applying one or more wavelet transforms to generate multiple coefficients and storing N bitplanes of each of the multiple coefficients in a first memory having multiple rows. Each of the multiple coefficients has a bit length greater than N bits, and each storage location in each of the rows stores a bit of either a more significant bitplane of the coefficients or a less significant bitplane of the coefficients. The storing of N bitplanes includes storing an indication for each row of the rows to indicate a location in each row at which bits of more significant bitplanes have started to be stored and after which bits of the multiple coefficients of the less significant bitplanes are no longer stored.

In one embodiment, the method comprises decomposing input data into a plurality of code-blocks, and assigning the plurality of code-blocks, on a code-block basis, to a plurality of MQ coders to code the plurality of code-blocks in parallel to balance, to the extent possible, an amount of coding to be performed by each of the plurality of MQ coders.

Abstract: A multi-resolution segmentation and fill technique is disclosed. In one embodiment, the method comprises generating a plurality of layers using image data from multiple resolutions, generating a mask describing compositing of the plurality of layers to obtain the image, and filling pixels in each of the plurality of layers where the pixels being filled are those that do not contribute to the image when the plurality of layers are composited.

Abstract: A method and apparatus for encoding and decoding data that includes generating transformed signals in response to input data. In one embodiment, the transformed signals are generated using a reversible wavelet transform. The present invention also includes a method and apparatus for compressing the transform signals into data representing a losslessly compressed version of the input data. In one embodiment, the present invention decomposes the input data using reversible wavelet transforms.

Abstract: A method and apparatus for performing block sequential processing is described. In one embodiment, the apparatus comprises a determine pass logic, selection logic, next coefficient logic and control. The determine pass logic has inputs coupled to receive significance state information for a region, a pass bit for each coefficient in a subset of the region, and a current pass indication. In response to these inputs, the determine pass logic generates pass indications to indicate a pass for each coefficient in the subset of the region. The selection logic has inputs coupled to signals output from the determine pass logic and the current pass indication and, in response to these inputs, generates output indications associated with one pass of either the significance propagation, refinement, and cleanup passes. The next coefficient logic is coupled to the selection logic and indicates the next coefficient in the current pass in response to the output indications from selection logic.

Abstract: A 5,3 wavelet filter is disclosed.

Abstract: A system and method for providing control by and author over the dissemination of information contained in a blind carbon copy electronic message. The author may specify whether or not a BCC recipient may reply to the author, reply to any of the other message recipients, forward the message, copy, save or print the message. If a BCC recipient attempts to perform a controlled dissemination action, the author may elect to be notified of the attempt, to notify the BCC recipient of the surveillance, and to optionally authorize the performance of the dissemination operation. Additionally, the author may delay the performance of the dissemination action according to a schedule or time delay specified by the author.

Abstract: The present invention is directed toward a flexible plastic platen used as a document support surface in a copying/printing machine. The platen, in a preferred embodiment, is an optically clear polycarbonate sheet, inexpensive and easy to handle. The platen is mounted in a machine frame so as to be slightly flexed upward along a width area corresponding to the area to be scan-illuminated to ensure accurate focusing of the document image through an underlying linear lens array. The platen is easily replaced by releasing the tension and lifting the platen out of a seated position.
