3D Image Coding Techniques
Motion compensation is utilized in Stereoscopic Video Coding
In video, time is often considered as the third dimension. Still image coding techniques can be expanded to an extra dimension.
JPEG2000 uses wavelets, and these can also be used to encode motion without gaps between blocks in an adaptive way. Fractional pixel affine transformations lead to bleeding between adjacent pixels. If no higher internal resolution is used the delta images mostly fight against the image smearing out. The delta image can also be encoded as wavelets, so that the borders of the adaptive blocks match.
2D+Delta Encoding techniques utilize H.264 and MPEG-2 compatible coding and can use motion compensation to compress between stereoscopic images.
Expanding the 8x8 JPEG blocks into the third dimension that is into 8x8x8 cubes and modifying the DCT more into a DFT enables compression of linear translations with speeds below and around one pixel per frame (sub-pixel precision).

Famous quotes containing the words image and/or techniques:
“Thou shalt not, it is said, make unto thee any graven image of God. The same commandment should apply when God is taken to mean the living part of every human being, the part that cannot be grasped. It is a sin that, however much it is committed against us, we almost continually commit ourselves—Except when we love.”
—Max Frisch (1911–1991)
“The techniques of opening conversation are universal. I knew long ago and rediscovered that the best way to attract attention, help, and conversation is to be lost. A man who seeing his mother starving to death on a path kicks her in the stomach to clear the way, will cheerfully devote several hours of his time giving wrong directions to a total stranger who claims to be lost.”
—John Steinbeck (1902–1968)
