Abstract
A data compression system is provided in accordance with the present invention. The system includes a scanning component which scans at least a portion of a transformed image. The scan is performed substantially in a horizontal direction on a first section of the portion and in a vertical direction on a second section of the portion to enable improved data compression of the transformed image. The horizontal and vertical scan directions are performed via a contiguous scan of the respective sections to further enable improved data compression of the transformed image.
Claims19
A data compression system, comprising:
- a scanning component which scans at least a portion of a transformed image, wherein the scan is performed substantially in a horizontal direction on a first section of the portion and in a vertical direction on a second section of the portion to enable improved data compression of the transformed image;
- and
- a quantizer that reduces stored data associated with wavelet coefficients that correspond to the transformed image.
A method for providing a data compression system, comprising:
- scanning at least a portion of a transformed image in substantially a horizontal direction on a first section of the portion;
- scanning in a vertical direction on a second section of the portion of the transformed image to enable improved data compression of the transformed image;
- and
- reducing data associated with wavelet coefficients that correspond to the transformed image.
A data compression system, comprising:
- means for scanning at least a portion of a transformed image in substantially a horizontal direction on a first section of the portion;
- means for scanning in a vertical direction on a second section of the portion of the transformed image to enable improved data compression of the transformed image;
- and
- means for reducing data associated with wavelet coefficients that correspond to the transformed image.
