Flexible data organization for images
View Patent ↗A system, a method and computer-readable media for encoding image data into a compressed bitstream. A mode selection component is configured to select a mode of operation for use in encoding image data. A spatial mode encoder is utilized when the mode selection component selects a spatial mode of operation. The spatial mode encoder is configured to encode the image data into packets by organizing the image data in accordance with a spatial partitioning. A frequency mode encoder is utilized when the mode selection component selects a frequency mode of operation. The frequency mode encoder is configured to encode the image data into packets by organizing the image data in accordance with a frequency ordering.
1. A system that encodes color-plane data of an image into a packet of a compressed bitstream, said system comprising:
a mode-selection component that selects a mode of operation from among a plurality of modes, wherein the mode of operation dictates an organization of the color-plane data when the color-plane data is encoded into the packet and wherein the color-plane data prescribes a rendering of one or more color planes of the image;
a spatial-mode encoder that is utilized when the mode-selection component selects a spatial mode of operation, wherein said spatial-mode encoder encodes the color-plane data into said packet by organizing the color-plane data into ordered macroblocks within at least a portion of said packet in accordance with a spatial partitioning; and
a frequency-mode encoder that is utilized when the mode-selection component selects a frequency mode of operation, wherein said frequency-mode encoder encodes the color-plane data into said packet by organizing the color-plane data within at least a portion of said packet in accordance with a frequency ordering.
2. The system of claim 1 , wherein the ordered macroblocks, when assembled together, comprise an independently decodable region of the image, and wherein the spatial partitioning divides at least a portion of said independently decodable region into one or more blocks.
3. The system of claim 1 , wherein said frequency ordering organizes the color-plane data associated with the packet into a plurality of bands.
4. The system of claim 3 , wherein at least one of said plurality of bands includes DC values associated with the packet.
5. The system of claim 3 , wherein at least one of said plurality of bands includes highpass or lowpass coefficients associated with the packet.
