Abstract: A method for distortion of a digital image comprising determining one or more sets of pixel characteristics, receiving for each pixel characteristic set, a spatial offset, providing a mixing function algorithm embodied on a computer-readable medium for distorting the digital image, calculating an offset matrix by applying the mixing function algorithm based on the one or more sets of pixel characteristics and the received spatial offsets, and distorting the digital image by application of the offset matrix. The method is applicable to regions of interest in the digital image, where the calculating step further comprises applying the mixing function algorithm based on the received coordinates of a region of interest. Abstract image reference points may be used to limit distortion.

Abstract: A method for distorting a digital image comprising receiving the coordinates of one or more than one image reference point defined by a user within the digital image, receiving one or more than one spatial offset assigned by the user and associated with the coordinates of the one or more than one defined image reference point, providing a mixing function algorithm embodied on a computer-readable medium for distorting the digital image, calculating an offset matrix by applying the mixing function algorithm based on the one or more than one spatial offset and the coordinates of the one or more than one defined image reference point; and distorting the digital image by application of the offset matrix. A graphic tag may be associated with each of the defined image reference points and displayed over the digital image, and the assignment of the spatial offset may be accomplished by movement of the graphic tag with the pointing device. Abstract image reference points may be used to limit distortion.

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 graphical user interface for execution on a computer for image processing of a digital image, and method, in which an input interface is overlaid on the digital image and visually connected to the coordinates of one or more pixels to be processed.
