Abstract
Embodiments of the present invention relate generally to visual degrading of images. Systems and methods for fast visual degrading of an entire image or localized region(s) within the image are provided. In an embodiment, a system for fast localized visual degrading of images includes a map creator and a coefficient list modifier. The map creator generates a map. The map may identify one or more degradation regions within an image. The coefficient list modifier reduces coefficient data in at least one block associated with a degradation region identified in the map. In another embodiment, a computer-implemented method for fast localized visual degrading of images is provided. The method includes generating a map that identifies one or more degradation regions within an image, and reducing coefficient data in at least one block associated with a degradation region identified in the map.
