Abstract
The process for storing, in pages of a memory, image blocks (h, v) consisting of v lines of h pixels, for the reading of image blocks (H, V) consisting of V lines of H pixels, is characterized in that the horizontal shift DI, I+a, in terms of number of blocks (h, v), of the boundary of a page corresponding to any row I of the image with respect to the boundary of a page corresponding to a row I+a is equal to:DI, I+a=a D, ∀ positive integer a less than RM=INT [(V−2)/v]+2,(INT corresponding to the integer part of the division)the value D, which corresponds to the shift between two successive rows being chosen such that:D≧(BM−1), with BM=INT [(H−2)/h]+2.Applications relate, for example to motion estimation and motion compression.
