Aggregation and refinement in binary image restoration
Michael Jubb, Christopher Jennison · Lecture notes-monograph series · 1991
The work reported in this paper grew out of an investigation into the use of "refinement" methods to obtain restorations of an image with detail at a level finer than the pixel grid on which records are observed.A "cascade" algorithm is presented that produces restorations on successively finer pixel grids, starting with a single large pixel and ending with the original grid.
