The disclosure includes a system and method for aggregating form data based on marks in graphic form fields. The system includes a controller, a request customization module, a search module and a presentation module. The controller receives data indicating an initiation of a search request from a user, data describing a form selected by the user, data describing a graphic form field specified by the user in the form and data describing a region of interest specified by the user in the graphic form field. The request customization module customizes the search request using the region of interest. The search module performs a form search on a collection of form data using the search request to determine one or more matching forms that each include at least one mark satisfying the region of interest. The presentation module provides the one or more matching forms to the user.

A method and apparatus for reformatting electronic documents is disclosed. In one embodiment, the method comprises performing layout analysis on an electronic version of a document to locate text zones, assigning attributes for scale and importance to text zones in the electronic version of the document, and reformatting text in the electronic version of the document based on the attributes to create an image.

A secure system for executing program code in an insecure environment while making it impossible, or at least impractical, to determine how to copy the program code and associated data is provided. A program memory contains encrypted program data and security circuitry contained within an integrated circuit is provided for decrypting the program data as it is needed by a processor. A portion of the processing steps which would be done by the processor in an insecure system is performed in this secure system within the secure circuitry using portions of the decrypted program data which are not provided to the processor. Program data is parsed it out based on a proper request to the security chip from the processor. A key value stored in volatile memory is used in the decrypting process and the volatile memory is positioned on the integrated circuit such that its contents are lost before a chip peel provides access to the volatile memory.

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.
摘要:
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.
摘要:
A method and apparatus for performing selective quantization by manipulation of refinement bits is described. In one embodiment, the method comprises performing a refinement coding pass to bit-planes of a code block to create refinement bits and setting refinement bits to the more probable symbol (MPS).
摘要:
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 decoding information using late contexts is described. In one embodiment, a decoder for decoding information using an MQ-coder and A and C registers comprises update logic to update internal state, a first logic to generate a current probability class indication in response to a context, wherein updating of the internal state by the update logic overlaps at least one while generating the context or generating the current probability class indication, probability class generation logic to generate a pair of probability class indications associated with an interval specified by the A and C registers in response to a codestream, comparison logic coupled to the first logic and the probability class generation logic to determine whether a probability class corresponding to the current probability class indication is within a range of probability classes corresponding to the pair of probability class indications, and output logic coupled to the comparison logic to output a decision based on results of comparison between the current probability class indication and the pair of probability class indications.
