Abstract: Method for blending a foreground object of a first image into a second image in which the transition boundary region between the foreground object and the background comprises a linear color transition based on the colors of the foreground object and the background, respectively.

Abstract: An apparatus and method for segmenting a digital image into image segments includes selecting one or more pixels in an image to define an initial pixel selection, determining a final pixel selection which includes those pixels in the image that are contiguous with the initial pixel selection and that have sets of n values corresponding to points in an n-dimensional space in the same characteristic segments as those points corresponding to the sets of n values of pixels in the initial selection. The pixel values of the final pixel selection are assigned to a first image segment such that the visual characteristics of the pixels of the first image segment may be modified independently of other pixels.

Abstract: By using homotopic transformations, specifically the watershed transformation, within feature space formed by the red, green and blue components, or any other set of attributes, of the pixels of an image, a unique number of colours can be found for that image. Each colour is given a label and the image is then segmented into regions of uniform labels. The colour or characteristic of each segment can then be altered or used to identify, an object. This can be applied to any scalable (either integer or real) data set.
