Abstract COMPRESSION OF HIGH BIT-DEPTH IMAGES 5 A method of storing an image is disclosed. A high bit-depth frequency-domain representation of the image is received and divided into a first bit-plane portion and a second bit-plane portion. The first bit-plane portion has a higher bit-plane than the second bit-plane portion. Each of the first bit-plane portion and the second bit-plane portion is partitioned into a plurality of partitions. At least one partition from the second bit-plane portion is inserted 10 into the plurality of partitions of the first bit-plane portion to produce a plurality of arranged partitions of the image. The arranged partitions of the image is stored. 991878_Final (5394750v1) -7/ 13 700 Start Receiving a high bit-depth 701 frequency-domain representation of the image Dividing the high bit-depth 710 frequency information into a high bit-plane portion and a low bit-plane portion Quantize the high bit-plane 720 portion and the low bit-plane portion Partition the high bit-plane 730 portion and the low bit-plane portion into a plurality of quality partitions Store the quality partitions 740 from the high bit-plane and the low bit-plane with priority based on overall quality End Fig. 7 5394717vl |
