A new predictive video-coding technique, using fmctalimage compression for intrafmme coding and second order geometric tmnsfomations for moiion compensation in interframe prediciive coding, is pmsenied. I n order to reduce the amount of data required io digatally transmit o r siore a sequence of images, a meihod, describing lhe subsequent images as a set of geometric lrartsfonnations of parts of the previous images, is used. For that purpose, the first image in the sequence arid the difierence between the pwdicted and the actual new image are jmdal-coded using blockwise conimclive afline lransformations. For motion compensaiion second order geometric tmnsformations, compensating for tmnslation, rotalion, zooming, uneven siretching, and any combination of these, has been used. The decoded images can be displayed al arbitrary resolution without blockiness, which, together with the very high compression ratio achievable, is the mod important advanloge of lhe fractal-based image coding technique over the standrd DCT-based image coding.
