Claim One:
1. A method of segmenting an arbitrary first image feature in a selected video image frame from an adjacent second image feature in the selected video image frame, the arbitrary first image feature having plural pixels of a first spatial image characteristic and motion relative to the second image feature between the selected video image frame and a preceding video image frame, and the second image feature having plural pixels and a second spatial image characteristic different from the first image characteristic, comprising: obtaining a motion representation of corresponding pixels in the selected video image frame and the preceding video image frame; segmenting the first and second video image features according to the motion representation to form first and second motion segmented video image features; segmenting the first and second video image features according to the respective first and second spatial image characteristics to form first and second spatially segmented video image features; and forming jointly segmented first and second video image features as a weighted sum of the first and second motion segmented video image features and the first and second spatial segmented video image features; wherein the first and second motion segmented image features are computed independently from the first and second spatial segmented video image features.
