Abstract: Method and apparatus for archiving media using a log are described. In one embodiment, the method comprises accepting an original media; updating a first log to include an indication that specifies a date of when the original media was received; converting the original media into a bitmap, the bitmap being in a format different than that of the media; updating a second log with an entry that specifies a relationship between the original media and the bitmap indicating that they are related, wherein the entry includes an identifier corresponding to the entry and an identifier corresponding to the media.

Abstract: Method and apparatus for recording associations with logs are described. In one embodiment, the method comprises obtaining a first media identifier corresponding to a first media; accessing a log that contains one or more entries that associate two or more media identifiers with each other; and determining that the first media is related to a second media based on the log indicating that a second media identifier is associated with, but different from, the first media identifier.

Abstract: Method and apparatus for process logging are described. In one embodiment, the method comprises accessing a log having one or more log entries that contain a first data indicative of a set of one or more processing operations, a second data indicative of an input to the one or more processing operations, and a third data indicative of an output of the one or more processing operations; and verifying one or more processing operations were performed based on information in one or more of the log entries of the log.

Abstract: An encoding process and a recompression process of encoded data are disclosed that appropriately select low-order bit planes and low-order sub bit planes, codes corresponding to which are not to be output. The low-order bit planes and low-order sub bit planes are selected based on an inverse value of the square root of the subband gain of inverse wavelet transform, such that the selected low-order bit planes and low-order sub bit planes are not encoded, or alternatively, are encoded, but later discarded during packet generation.

Abstract: A system is described. In one embodiment, the system comprises an image processing path and a print engine coupled to the image processing path. The image processing path processes an input image in a wavelet domain.

Abstract: 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.

Abstract: A multimedia output device having embedded encryption functionality enables the outputting of content in an encrypted form. The multimedia output device receives the content to be encrypted, encrypts the content, and generates an electronic output of the encrypted content. The multimedia output device also generates an associated paper output that provides information about the decryption, such as a key, an identification of the electronic output of the encrypted content, and optionally a description of the contents of the content encrypted.

Abstract: A method and apparatus is disclosed herein for processing document images. In one embodiment, the method comprises extracting one or more features corresponding to one or more objects from a JPM compressed file, including extracting at least one of the one or more features without decoding, ranking document objects based on a task being performed by an application, and the one or more extracted features, and selecting a set of the document objects based on rank and at least one constraint.

Abstract: A method, apparatus and article of manufacture for network access of partial document imagery is described. In one embodiment, the method comprises receiving a request for a region of a page of a document, the request being originated from a client, determining one or more objects in a source file that intersect the region of the page, the source file having two or more codestreams, and sending a response having a subset of the information in the file.

Abstract: A method of generating an output image having a lower resolution than that of a source image is provided. A thinned image is generated by discarding outer pixels of the source image. In parallel with generation of the thinned image, an averaged image is generated, such that each pixel of the averaged image represents an average of a subset of pixels in the source image. A first output image is then generated by subsampling the pixels of the thinned image. A final output image is generated as a function of both the first output image and the averaged image.

Abstract: A method and apparatus for creating visualizations using tree functionals is described. In one embodiment, the method comprises representing a group of document images using a plurality of visualizations that visualize document layout information for the group of document images based on one or more display device characteristics and based on content of the group of documents, and adapting the plurality of visualizations to an available display by removing one or more visualizations from the plurality of visualizations based on at least two functional values.

Abstract: A method and apparatus for enhancing compressed images is described. In one embodiment, the method comprises characterizing quantization noise in reconstructed low pass coefficients generated in response to application of an inverse wavelet transform and removing the quantization noise from the reconstructed low pass coefficients constructed during decoding.

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 system and method for paper-based, automated completion of forms allows a user charged with filling out multiple forms containing some common information to write each unique piece of information one time, and the system generates a set of completed forms with the required information on each form with no change to the use or structure of the current forms. The control module is operable on a processor to determine a mapping between common fields on multiple forms or multiple pages of the same form, copy information written in a field on one form to equivalent fields on other forms, and produce a set of completed forms. The system is computationally simple and independent of language because these operations can be performed without having to understand, translate or convert the writing. Furthermore, there is no loss of security or privacy beyond the use of paper forms because these operations can be performed without access to a centralized database and without connectivity to other systems.
