摘要:
Calibration for plenoptic imaging systems. The calibration preferably is performed automatically by a processor. In one approach, the processor accesses a plenoptic image captured by the plenoptic imaging system. The plenoptic image is analyzed to determine reference points for superpixels of the plenoptic imaging system, for example the centers of the superpixels. The reference points are used to determine a location of each superpixel relative to the detector array.

A method, apparatus and article of manufacture for creating visualizations of documents are described. In one embodiment, the method comprises receiving an electronic visual, audio, or audiovisual content; generating a display for authoring a multimedia representation of the received electronic content; receiving user input, if any, through the generated display; and generating a multimedia representation of the received electronic content utilizing received user input.
摘要:
Metrics for characterizing the focusing of a plenoptic imaging system. In one aspect, the metric is based on the high frequency content and/or the blurring of the plenoptic image.
摘要:
A method and apparatus for printing from mobile devices are described. In one embodiment, the method comprises outputting a machine-readable code associated with the printer; receiving rendered print data specified by the mobile device that scanned and decoded the machine-readable code; and printing the rendered print data.
摘要:
A method and apparatus for image processing is described. In one embodiment, the method comprises accessing header data from a multi-resolution codestream of compressed data of a first document image, deriving one or more retrieval attributes from the header information, and performing image analysis between the first document image and a second document image based on the one or more retrieval attributes.
摘要:
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.
摘要:
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.
摘要:
A method and apparatus for visualizing results from a text search engine are described. A query term is first received. A first set of results is generated based on the query term using a database storing documents, and an index of documents, each document having at least one structural element. Structural elements associated with the first set of results are retrieved. A second set of results is generated based a predefined relationship between the structure elements and the query term. A visualization of the second set of results is displayed.
