Remove watermark image filter

         Adding watermarks to photos is a common practice in image processing. However, there are instances where the opposite, and more intricate, task becomes necessary - removing watermarks. Your images might be disfigured by the inclusion of technical data that needs to be eliminated before publication. In such cases, employing a watermark removal image filter is a highly effective solution.

         Remove watermark filter is designed to automatically remove watermarks, but for optimal usage, you must initially define the coordinates of the watermark's location. The filter offers a range of removal mode settings. You can select the algorithm to be employed for filling the watermark area and specify the maximum number of attempts. It's worth noting that increasing the number of attempts enhances the final result but demands more computational resources.
