Image Processing Systems Employing Image Compression And Accelerated Decompression

US Patent:
8170335, May 1, 2012
Filed:
Oct 13, 2011
Appl. No.:
13/272633
Inventors:
Eric Balster - Dayton OH, US
Mike Flaherty - Kettering OH, US
Benjamin Fortener - Centerville OH, US
David Lucking - Kettering OH, US
Thaddeus Marrara - Dayton OH, US
David Mundy - Dayton OH, US
Frank Scarpino - Centerville OH, US
Ken Simone - Miamisburg OH, US
William Turri - Beavercreek OH, US
Nick Vicen - Oakwood OH, US
David Walker - Dayton OH, US
Assignee:
University of Dayton - Dayton OH
International Classification:
G06K 9/00
US Classification:
382166, 382173
Abstract:
A system for processing an image includes a non-transitory memory component storing a set of executable instructions, and a scalable tile processing device. The executable instructions cause the system to receive image data, partition the image data into tiles, transmit a tile to the scalable tile processing device, receive an encoded bit stream corresponding to the transmitted tile from the tile processing device, output compressed image data including the encoded bit stream, receive the compressed image data, decode the compressed image data to generate a plurality of decoded code blocks, and output decompressed image data including the plurality of decoded code blocks. The scalable tile processing device receives the tile including tile image data, wavelet transforms, quantizes, segments, and encodes the tile image data to generate a plurality of encoded code blocks, and transmits an encoded bit stream including the plurality of encoded code blocks to the system.

Abstract:
A system for processing an image includes a an image data input port, a compressed image data output port or a compressed image data storage node, a non-transitory memory component storing a set of executable instructions, and a scalable tile processing device. The executable instructions cause the system to receive image data, partition the image data into tiles, transmit a tile to the scalable tile processing device, receive an encoded bit stream corresponding to the transmitted tile from the tile processing device, and output compressed image data including the encoded bit stream.
