Abstract:
Some fracta l curves, such asH ilbert curves, Z curves and quad-tree, can fill in a rectang le in a plane. Th is property could be used in coding, compression and index ing of image. B ased on the fracta l tree, an index method ( image index based on fracta l address, IFA ) is analyzed. Themethods are sim ilar to binary tree in structure, w ith each node representing the sum of the g rey scale in every image section. It can fu lly present the g rey sca le o f every section in an image and help to image c lassif ication, index and recogn ition. W ith them ethods be ing improved, nXn nodes can ind icate n @n im ages layer by layer. A ccord ing ly, index and sto rage are integ rated through the index structure. The paper introduced one of the methods concern ing how to change 2 r to 2 r + 1 - 1 subsequence into r-H ilbert sequence, and thew ay o f ca-l culat ing the IFA sequence o f each point on an image w as also presen ted. A t las,t the application and fracta l index based on the content o f an image w ere d iscussed.
