Claim One:
1. Apparatus for processing of an image, the apparatus comprising: a pixel input configured for handling pixels of said image, the pixel defining a local property; a reference input configured for user interactive definition of reference points; an interpolation unit associated with said pixel input, configured for applying an interpolation of attributes at a respective pixel based on said reference points; and a property assigner configured to compare a local property with said interpolation to apply a function to said local pixel based on said comparison using the said interpolated attributes, thereby to modify said local pixel, wherein said function is keying, said image comprising a foreground, said foreground comprising an object and a surrounding part to be removed, said reference points being sample points of said background to be removed and said function comprising assigning a level of opaqueness to said local pixel based on said comparison, thereby to remove the part from the image, wherein said reference input comprises a user setting unit for allowing a user to define said part to remove by identifying points thereon, said interpolation comprising providing a local set of keying attributes to correspond to said respective pixel, said local background color being an interpolation obtained from the colors at the identified points by weighting of their distances to said respective pixel, said distances being geometric distances.
