Abstract: A method for image processing of a digital image, in which a region of interest is defined in the digital image, one or more sets of pixel characteristics are determined for the region of interest, along with an image editing function, and the digital image is processed by applying a mixing function algorithm based on the one or more sets of pixel characteristics and the determined image editing function. When the digital image includes pixels that are outside of the region of interest, the processing the digital image includes using the mixing function to determine which pixels that are outside of the region of interest are affected by the image editing function.

Abstract: A method for image processing of a digital image comprising the steps of determining one or more sets of pixel characteristics; determining for each pixel characteristic set, an image processing filter; providing a mixing function algorithm embodied on a computer-readable medium for modifying the digital image; and processing the digital image by applying (22) the mixing function algorithm based on the one or more pixel characteristic sets and determined image processing filters. Various mixing function algorithms are described. An application program interface embodied on a computer-readable medium comprising a first interface to receive the coordinates of the image reference points, and a second interface to receive assignment of the image processing filter is also provided. The application program interface may represent the image reference points by a graphic tag (10).
