摘要:
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.

A method, apparatus, and article of manufacture for collecting and exchanging data are disclosed. In one embodiment, the apparatus comprises a non-volatile memory device, which includes an interface for coupling the non-volatile memory device to a host system; non-volatile memory for storing data, including a plurality of executables at least two of which are executable on different operating systems or devices. The plurality of executables includes a data collection executable and a data transfer executable. The non-volatile memory device also includes a controller to cause execution of at least one executable in the plurality of executables, including the data collection executable and the data transfer executable, where execution of the data collection executable causes data to be collected and stored in the non-volatile memory, and execution of which causes the collected data to be transferred to a location external to the non-volatile memory device.

A method and apparatus is described for segmenting an image, for adaptively scaling an image, and for automatically scaling and cropping an image based on codestream headers data. In one embodiment, a file that can provide a header that contains multi-scale entropy distribution information on blocks of an image is received. For each block, the block is assigned to a scale from a set of scales that maximizes a cost function. The cost function is a product of a total likelihood and a prior. The total likelihood is a product of likelihoods of the blocks. The image is segmented by grouping together blocks that have been assigned equivalent scales. In one embodiment, the file represents an image in JPEG 2000 format.

A document serving system includes at least one client interaction module and a multifunction peripheral with an integrated server (or document processor & server) for processing, storing, receiving and sending image and data files. The document serving system receives an original image or document file and stores the original file at the integrated server. The document serving system generates an Independently Usable Image (IUI) file that is smaller in size, lower in resolution and includes at least one reference to the original file. The IUI file can be sent to and manipulated by the client devices. The integrated server includes a receipt and storage module, a transmission module, a display interaction module, a creation module and a printer interaction module. The present invention also includes a number of novel methods including: a method for generating an IUI file, a method for processing and storing an original image file, and a method for serving documents.

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.

A method and apparatus for eliminating flicker by quantizing values based on previous quantization is described. In one embodiment, the method comprises encoding a first coefficient value in a first frame of a motion sequence and subsequently setting a second coefficient in a second frame of the motion sequence and in the same position as the first coefficient to be within a predetermined closeness with the value of the first coefficient.
