A device includes a processor and associated memory; and a compressor for compressing data representing an electronic document, the electronic document comprising a number of objects. The compressor is to determine for each object of the document whether data of that object is to be compressed with lossy or lossless compression and to compress the data accordingly to generate a compressed electronic document.

A scanner redirection method for a remote desktop system that includes a client computing device that has running therein a scanner redirection module, and a host server, the scanner redirection module including a data source manager for communicating with a data source that is configured to communicate with a physical scanner, includes the steps of: receiving from an application running on the host server, a request for a scanned image; in response to the request for the scanned image, transmitting to the data source a request to acquire the scanned image from the physical scanner; and upon receiving the scanned image from the data source, transmitting the scanned image to the application.

An image processing method is provided for acquiring additional information from image information obtained by shooting a printed product on which the additional information is multiplexed by at least one of a plurality of different multiplexing methods, the method comprising: attempting decoding of the additional information from the image information by a plurality of different decoding methods corresponding to the plurality of different multiplexing methods; and outputting, by a unit, the additional information successfully decoded.

A data-bearing image (391) is created from a carrier image (371). The carrier image (371) is scaled to produce a scaled image. A clustered-dot halftone screen is applied to the scaled image to produce a halftone image. A resulting number of cells in the halftone image conforms to a cell count (372) that includes a horizontal cell value and a vertical cell value. Payload data is encoded into the halftone image to produce a data-bearing halftone image, including shifting pixel clusters within cells of the halftone image that include pixel clusters.

A method and device for determining a boundary associated with image data captured by an electronic device is provided. The electronic device may include a camera. In one aspect, a method includes: capturing the image data using the camera; based on the captured image data, detecting a boundary marker displayed by a display device, the boundary marker is periodically displayed to be undetectable by a human eye that is viewing the display device; and modifying, based on the boundary marker, image data captured by the camera.

A method and a system for transmitting data are provided. In a source apparatus, original data is divided into a plurality of source segments, a similarity calculation is performed for each of the source segments to obtain a similarity set, and the similarity set is transmitted to a target apparatus. In the target apparatus, whether a target segment corresponding to the source segment exists in the target apparatus is determined according to the similarity set to obtain a comparison result, and the comparison result is transmitted to the source apparatus. In the source apparatus, after the original data is dehydrated according to the comparison result to obtain dehydration data, the dehydration data is transmitted to the target apparatus. In the target apparatus, the dehydration data is rehydrated to the original data.

A system and method adaptively lossy compresses image data by receiving a pixel of image data and meta data indicating a type of object that generated the pixel of image data, the pixel of image data includes a first byte having most significant bits of image data and a second byte having least significant bits of image data; electronically determining if the meta data associated with the pixel of image data is associated with a noisy image or indicates that the pixel of image data was generated by a specific type of object; electronically modifying the pixel of image data, when it is determined that the meta data is associated with the pixel of image data is associated with a noisy image or indicates that the pixel of image data was generated by a specific type of object, by setting a predetermined number of low bits of the pixel of image data to zero.

An image processing method is provided for acquiring additional information from image information obtained by shooting a printed product on which the additional information is multiplexed by at least one of a plurality of different multiplexing methods, the method comprising: attempting decoding of the additional information from the image information by a plurality of different decoding methods corresponding to the plurality of different multiplexing methods; and outputting, by a unit, the additional information successfully decoded.

A scanner redirection method includes the steps of: receiving from an application running on a host server, a request for scanner properties; acquiring properties of the physical scanner; converting the properties of the physical scanner that are described according to a first scanning protocol to properties of the physical scanner that are described according to a second scanning protocol; transmitting the properties of the physical scanner that are described according to the second scanning protocol to the application; in response to detecting a user selection made on an image of a user interface, transmitting the user selection to the application; and in response to the user selection, receiving from the application, a request for a scanned image, and transmitting a request to an image capture core to acquire the scanned image from the physical scanner.

A cell phone is disclosed for acquiring information to be transmitted to a receiving facility and for transmitting such thereto. A capture device captures information from an external source. A processor is provided for associating with the captured information a representation of the date and time of the capture of the information, such that the representation of the date and time information in association with the captured information forms augmented captured information. The processor also places the augmented captured information in association with subscriber information in a transmission of the augmented captured information to a receiving facility requiring such subscriber information. A transmitter transmits the transmission including the augmented captured information and the subscriber information to the receiving facility. An encryptor encrypts the augmented captured information with a symmetrical encryption algorithm to provide encrypted augmented captured information in the transmission with the subscriber information.
