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.

A method and apparatus for assigning codeblocks to coders operating in parallel is described. 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.

A method and apparatus for clipping coefficient values after application of each wavelet transform is described. In one embodiment, the method comprises applying an inverse wavelet transform to data repeatedly for a plurality of decomposition levels, and clipping, after each application of the inverse wavelet transform, any value generated as a result of application of the inverse wavelet transform that exceeds a predetermined range associated with that decomposition level subband of the inverse wavelet transform.

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 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 technique for removing blank space from an input page that includes a plurality of lines of text is provided. A plurality of objects are defined to represent the lines of text. A size is determined for an output page, such that the output page is smaller than the input page. It is then determined whether all the objects fit within the output page. If not, then the size of the output page is increased according to a predetermined amount, and this action is repeated as necessary until all the objects can fit onto the output page. The objects are then located on the output page, which may include rearranging the objects, as necessary, such that the relative positions of the objects in the output page are different from the relative positions of the objects in the input page.

An FSM-coder hardware is described. In one embodiment, the present invention provides a method of encoding that includes creating an interval based on a finite state machine (FSM) state. The interval comprises a pair of subintervals having endpoints. The method also includes selecting one of the pair of subintervals based on whether the input bit is in a most probable state, and outputting zero or more bits corresponding to bits that match between endpoints of said one subinterval that occur from the most significant bits to, and not including, the first non-matching bits between the endpoints of said one subinterval.

An electronic writing solution server includes a stroke autocompletion application that comprises an autocompletion processor. The autocompletion processor loads a blank form for a user, the form being associated with a list of auto completion target, retrieves a set of regions and a first form identifier (ID) included in the list of auto completion targets, receives information about the user, identifies a set of potential completion lists from a plurality of potential completion lists stored in a database based on the set of regions, the first form ID and the information about the user, retrieves at least one stroke from the set of potential completion lists for a region in the set of regions, ranks the at least one stroke and provides the at least one stroke to the user.
摘要:
A system for paper-like forms processing includes a plurality of portable computing devices coupled by a network to a paper-like forms server. The portable computing devices are adapted to receive images (e.g., compound documents/forms), add stroke annotations to the received images, and send the annotated received images or the stoke annotations themselves to the paper-like forms server. The paper-like forms server comprises a central scheduler and a logging module. The paper-like forms server processes compound documents as paper like forms and sends input to and receives results from service providers to perform various types of paper like processing on the compound document. The paper-like forms server performs the scheduling, routing, logging, verification and billing for the paper-like processing of compound documents. The central scheduler also stores results from service providers for later retrieval.
