- W133546124 abstract "To reconstruct (approximate) an arbitrary surface using subsurfaces (patches) from a library of surfaces in an optimal way is an interesting algorithmic problem and has many applications in image processing. This paper presents an efficient algorithm for an optimal reconstruction of a query surface using patches from a reference library of surfaces, under the constraint that the smallest patch size is above some specified value. In this algorithm, a surface is given as an integer function f(x, y) over a finite 2-D grid. The algorithm partitions a query surface into patches in such a way that each patch is represented by a similar patch from a library surface, and the total difference between the query surface and the representing (composite) surface is minimized, where the boundary of a patch is not pre-determined but solely determined by the optimization process. By using a minimum spanning tree-based data structure, this optimization problem can be solved efficiently. An application of this technique in computational forensics is outlined." @default.
