Graphic user interface for adaption of parameters for an automatic logo removal algorithm and method for adaption of these parameters

摘要

A graphic user interface for adaption of parameters to be used as a starting point for an automatic logo removal algorithm for removing a logo (4) within a picture or a sequence of pictures, wherein the algorithm comprises the steps of: defining a block (6, 17) inside a picture, the block (6, 17) comprising at least a portion of the logo (4), defining a search area (8, 20, 24) surrounding the block (6, 17), wherein the search area (8, 20, 24) is defining a search window within the picture or within a temporarily preceding or subsequent picture, and searching a best match for the block (6, 17) inside the search area (8, 20, 24) for determination of a replacement source block (10) or for determination of a motion estimate between subsequent pictures, wherein the source block (10) or the motion estimate provide a basis for the automatic logo removal algorithm, and wherein the graphic user interface provides a graphic overlay visualization of the block (6, 17), source block and/or the search area (8, 20, 24) and provides a user controlled adaption of parameters to be used as a starting point for the automatic logo removal algorithm by allowing a user defined setting of the respective block (6, 17), source block (10) and/or search area (8, 20, 24).
