Abstract:
1. A method for enhanced image encoding, the method comprising: dividing, by an encoder executing on a computing machine, an image into at least two overlapping image sections according to a grid size and an overlap margin; computing, by the encoder, a lightweight index for each overlapping image section; comparing, by the encoder, the lightweight index for each overlapping image section to lightweight indexes associated with stored image blocks; identifying, by the encoder responsive to the comparison of lightweight indexes, a first match between at least one stored image block having a first lightweight index substantially similar to a first lightweight index computed for the at least one overlapping image section; computing, by the encoder, in response to the first match, a first heavyweight index for the at least one overlapping section; comparing, by the encoder, the first heavyweight index with a second heavyweight index associated with the at least one stored image block; confirming, by the encoder responsive to the comparison of heavyweight indexes, the first match; assigning, by the encoder to the at least one overlapping image section, in response to the confirming, a pointer to a storage location of the at least one stored image block; and transmitting the pointer and overlapping image sections not assigned to the pointer to a second computing machine.
