System and apparatus for remotely printing certified documents

Abstract: A communication system for remotely and securely printing certified checks via the Internet includes a customer communication device operative to initiate communication with a web server which is in communication with a system bank capable of creating an image file of the certified check which is securely encrypted and transmitted back to the customer via the Internet.

Compression and reconstruction of radiological images

Abstract: The present invention provides for a compression scheme tailored to the compression of large radiological images processed with image processing workstations The compression scheme is a variation of the CCITT JPEG compression scheme with special care taken to suppress blocking effects of the 8×8 discrete cosine transform used therein In accordance with the present invention, an original image is downsampled, then interpolated back to its original size, resulting in a smoothed image The difference between the smoothed image and the original image is then compressed using an 8×8 discrete cosine transform with 12 bit data Major artifacts present in the original image are due to the mismatching of the low frequency components of the image at the edges of the blocks When the low frequencies are removed by subtracting out the low frequency components, the artifacts disappear except in areas having very large dynamic changes The compression scheme of the present invention is particularly useful for archiving or telecommunicating images, achieving compression of more than 10:1 without loosing the characteristics of the radiological image that permit effective diagnosis A reconstruction scheme is also disclosed which allows recovery of the image from a compressed image file

Method and system for extending the available image file formats in an image capture device

Abstract: A system and method for adding file formats to a digital imaging device is disclosed. The digital imaging device includes a built-in file format. The method and system include allowing a user to loading a first file extension module, providing a management layer, and providing a plurality of data processing utilities. The first file extension module includes a second file format. The management layer communicates with the first file extension module to write and read an image file having the second file format. The management layer also communicates with a portion of the digital imaging device using an internal format. The plurality of data processing utilities are for converting data to between the second file format and the internal format.

Data delivery apparatus and data delivery method

Abstract: A data delivery apparatus includes a first obtaining section, a second obtaining section, and a delivery section. The first obtaining section obtains a master image. The master image is a first image file generated from master data used in common for constructing different systems in the plurality of information processing apparatuses. The second obtaining section obtains a difference image. The difference image is a second image file generated from difference data specifying details of modification to the master data to construct an individual system. The delivery section delivers the master image and the difference image to the plurality of information processing apparatuses over a network.
