Abstract
Embodiments include methods for image compression and decompression. A sending computing device may determine a type of packing used for a chunk of image data, generate metadata describing the type of packing used for the chunk of image data, pack the chunk of image data according to the determined type of packing, and send the packed chunk of image data and the metadata to a second computing device. A receiving computing device may decode the metadata describing the type of packing used for the chunk of image data, determine the type of packing used for the chunk of image data based on the decoded metadata, and unpack the chunk of image data according to the determined type of packing used for the chunk of image data.
Claims30
A method performed by a processor of a computing device for image compression, comprising:
- determining a type of packing of a chunk of image data;
- generating metadata describing the type of packing used for the chunk of image data;
- packing the chunk of image data according to the determined type of packing;
- and
- sending the packed chunk of image data and the metadata to a second computing device.
A method performed by a processor of a computing device for image decompression, comprising:
- decoding metadata describing a type of packing used for a chunk of image data;
- determining the type of packing used for the chunk of image data based on the decoded metadata;
- and
- unpacking the chunk of image data according to the determined type of packing used for the chunk of image data.
A wireless device, comprising:
- a processor configured with processor executable instructions to perform operations comprising:
- determining a type of packing used for a chunk of image data;
- generating metadata describing the type of packing used for the chunk of image data;
- packing the chunk of image data according to the determined type of packing;
- and
- sending the packed chunk of image data and the metadata to a second computing device.
