摘要:
A scanning device includes a scanning mechanism and a processing mechanism. The scanning mechanism scans an image fixed on a medium to generate a digital infrared representation of the image and a digital visible light representation of the image. The processing mechanism substantially reduces effects of noise and distortions within the digital visible light representation of the image in one pass. The processing mechanism at least decorrelates visible light aspects from the infrared representation of the image and employs a one-pass filter that uses both the infrared and the visible light representations of the image.

Method and system embodiments of the present invention are directed to automated identification of regions within digitally-encoded images that correspond to objects and features of scenes captured in the digitally-encoded images, a process referred to as ‘perceptual segmentation’ of an image. Regions or segments within an image are first identified by any of various region-identifying or segmentation methods. For each region or segment, features of pixels within the region or segment are employed to compute one or more segment features. The segment features are used, in turn, to identify the region or segment as belonging to a particular type of region or segment, and the region is then accordingly labeled or tagged as a region or segment of the determined type.

A method for compressing a digital image to be printed, the image consisting of pixels. It is determined, for blocks of pixels, whether a block contains a graphical structure that is to be maintained without loss because it is of a type that can be accurately perceived by a human observer. The block is encoded losslessly into a less voluminous format, if such a graphical structure has been found. Otherwise, the block is compressed lossily, if no such graphical structure has been found.

In one aspect, an image is quantized by assigning sub-ranges of pixel values in the image to respective quantization levels. The quantized image is encoded based at least in part on a mask lookup table assigning index values to respective masks, wherein each mask corresponds to a respective spatial distribution of the quantization levels. In another aspect, a code corresponding to an encoded image with pixel values quantized to respective quantization levels is received. The code is decoded based at least in part on a mask lookup table assigning index values to respective masks, wherein each mask corresponds to a respective spatial distribution of the quantization levels.

In one implementation, a graphical object classification system includes an acquisition module, a signature generation module, and a classification module. The acquisition module accesses a representation of a graphical object. The signature generation module generates an appearance-invariant signature of the graphical object based on the representation. The classification module classifies the graphical object based on the appearance-invariant signature.

A method of providing community networking services in an organization creates a graph which has a plurality of people nodes representing persons in the organization and a plurality of content nodes representing content objects authored by the persons. The nodes are connected by edges, which include author edges linking the content objects to the persons and similarity edges each linking two content objects and having a similarity value indicative of a conceptual similarity between said two content objects. The graph is analyzed to compute a relevance value between a focus node and a query node in the graph.
摘要:
A method for integrating a plurality of existing software applications is disclosed. The method comprises executing the plurality of existing software applications. A composite graphical user interface (GUI) is created containing selected objects. A user's interactions with each of the plurality of existing software applications are recorded to record at least one function from each of the plurality of existing software applications. The at least one recorded function from each of the plurality of existing software applications is assigned to at least one of the selected objects in the composite GUI.
