Abstract

Abstract There is provided a system and a method thereof for producing enhanced signals from an irreversible compression first processor in which there were performed irreversible compression encoding of signals and subsequently a compression decoding thereof. The method includes defining at least two sets of signals, wherein each set contains signals having a selected property of a signal, feeding the decoded signals of the first processor to a second processor, and processing the decoded signals by the method of projection onto convex sets, thereby imposing conformity to the sets of signals.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 102 words
In a method for producing enhanced lossy signals from an irreversible compression first processor in which there is performed irreversible compression encoding of input signals and subsequently said enhanced signals are transferred to a second processor for performing compression decoding thereof, the improvement comprising: defining at least two sets of signals, wherein each set contains constraints including a multibit signal having a selected property of the decoded compressed signals; feeding the decoded signals representative of different colors to a third processor, and processing said decoded signals by the method of projection onto convex sets, thereby imposing conformity to said sets of signals.
Claim 2
Dependent Claim 102 words
In a method for producing enhanced lossy signals from an irreversible compression first processor in which there is performed irreversible compression encoding of input signals and subsequently said enhanced signals are transferred to a second processor for performing compression decoding thereof, the improvement comprising: defining at least two sets of signals, wherein each set contains constraints including a multibit signal having a selected property of the decoded compressed signals; feeding the decoded signals representative of different colors to a third processor, and processing said decoded signals by the method of projection onto convex sets, thereby imposing conformity to said sets of signals.
Claim 3
Dependent Claim 25 words
The method as claimed in claim 1, further comprising the step of pre-processing the compression-decoded signals prior to feeding the signals to said second compressor.
Claim 4
Dependent Claim 25 words
The method as claimed in claim 1, further comprising the step of post-processing the signals of said third processor for further enhancement of the signals.
Claim 5
Dependent Claim 29 words
The method as claimed in claim 3, wherein said post-processing signals are applied to an output device selected from devices for recording, printing or monitoring of said output signals.
Claim 6
Dependent Claim 25 words
The system as claimed in claim 1, further comprising a post-second processor for processing output signals of said third processor for a further enhancement thereof.
Claim 7
Dependent Claim 26 words
The system as claimed in claim 1, further comprising a recording or displaying device at least indirectly receiving signals from the output of said third processor.
Claim 8
Dependent Claim 109 words
In a system for producing enhanced lossy signals from an irreversible compression first processor in which there is performed irreversible compression encoding of input signals and subsequently said enhanced signals are transferred to a second processor for performing compression decoding thereof, the improvement comprising: means for defining at least two sets of signals, each set containing constraints including a multibit signal having a known property of the decoded compressed signals, and a third processor connected for receiving said sets of signals from said second processor and being of the kind which processes signals by the method of projection onto convex sets, thereby imposing conformity to said sets of signals.
Claim 9
Dependent Claim 109 words
In a system for producing enhanced lossy signals from an irreversible compression first processor in which there is performed irreversible compression encoding of input signals and subsequently said enhanced signals are transferred to a second processor for performing compression decoding thereof, the improvement comprising: means for defining at least two sets of signals, each set containing constraints including a multibit signal having a known property of the decoded compressed signals, and a third processor connected for receiving said sets of signals from said second processor and being of the kind which processes signals by the method of projection onto convex sets, thereby imposing conformity to said sets of signals.
Claim 10
Dependent Claim 25 words
The system as claimed in claim 7, further comprising circuit means for pre-processing the compression-decoded signals prior to feeding the signals to said second processor.
Claim 11
Dependent Claim 108 words
In a method for producing enhanced signals from an irreversible compression first processor in which there is performed irreversible compression encoding of input signals and subsequently said enhanced signals are transferred to a second processor for performing compression decoding thereof, the improvement comprising: defining at least two sets of signals, wherein each set contains constraints having a selected property of the decoded compressed signals and said sets are based on constraints representing correlation between separations of a color image; feeding the decoded signals to a third processor, and processing said decoded signals by the method of projection onto convex sets, thereby imposing conformity to said sets of signals.
Claim 12
Dependent Claim 108 words
In a method for producing enhanced signals from an irreversible compression first processor in which there is performed irreversible compression encoding of input signals and subsequently said enhanced signals are transferred to a second processor for performing compression decoding thereof, the improvement comprising: defining at least two sets of signals, wherein each set contains constraints having a selected property of the decoded compressed signals and said sets are based on constraints representing correlation between separations of a color image; feeding the decoded signals to a third processor, and processing said decoded signals by the method of projection onto convex sets, thereby imposing conformity to said sets of signals.
