Abstract
Abstract Measures for a motion compensation are combined with an image segmentation in four modes. In a first mode, a current picture is image-segmented before an estimation of a relative motion between a segmented region of the current picture and a corresponding region of a reference picture. In a second mode, a relative motion is estimated between a minute piece of a current picture and a corresponding minute piece of a reference picture, to be employed as a character parameter for an image segmentation. In a third mode, a relative motion is estimated between a sub-region of an image-segmented region and a corresponding small region, to be employed as a character parameter for a resegmentation. In a fourth mode, a relative motion between minute pieces is estimated to provide an additional character parameter for an image segmentation to be performed on a current picture, before a reestimation of a relative motion between an estimated region and a corresponding region.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
210 words
A method for processing a sequence of motion pictures, each motion picture comprising a plurality of picture elements, said method comprising the steps of: determining picture element information for each picture element in a current picture of said sequence of motion pictures, said picture element information including a plurality of components comprising a signal value of said each picture element, a coordinate position of said each picture element, and a motion estimation vector of said each picture element, said motion estimation vector being determined based on a position of said picture element in said current picture and a position of at least one corresponding picture element in a previous picture to said current picture; image-segmenting said current picture in said sequence of motion pictures into a plurality of first regions, wherein the image-segmenting is dependent on each component of said picture element information for each of said plurality of picture elements of said current picture; determining for each of said plurality of first regions a corresponding second region in said previous picture to said current picture in said sequence of motion pictures; and estimating a relative motion between each of said plurality of first regions and said corresponding second region to determine a motion vector representative of said relative motion.
Claim 2
Independent Claim
210 words
A method for processing a sequence of motion pictures, each motion picture comprising a plurality of picture elements, said method comprising the steps of: determining picture element information for each picture element in a current picture of said sequence of motion pictures, said picture element information including a plurality of components comprising a signal value of said each picture element, a coordinate position of said each picture element, and a motion estimation vector of said each picture element, said motion estimation vector being determined based on a position of said picture element in said current picture and a position of at least one corresponding picture element in a previous picture to said current picture; image-segmenting said current picture in said sequence of motion pictures into a plurality of first regions, wherein the image-segmenting is dependent on each component of said picture element information for each of said plurality of picture elements of said current picture; determining for each of said plurality of first regions a corresponding second region in said previous picture to said current picture in said sequence of motion pictures; and estimating a relative motion between each of said plurality of first regions and said corresponding second region to determine a motion vector representative of said relative motion.
Claim 3
Dependent Claim
101 words
A method according to claim 1, further comprising the steps of: motion-compensating a local decoded picture of said previous picture in dependence on said motion vector to obtain a predicted picture of said current picture; subtracting said predicted picture from said current picture to obtain a prediction error picture; coding said prediction error picture in a compressing manner into a set of coded data; decoding said set of coded data in a decompressing manner into a local decoded error picture; and adding said local decoded error picture to said predicted picture to obtain a local decoded picture of said current picture.
Claim 4
Dependent Claim
44 words
A method according to claim 1, wherein said current picture comprises an arbitrary picture in said sequence of motion pictures, and wherein said previous picture comprises a local decoded picture of a picture previous to said arbitrary picture in said sequence of motion pictures.
Claim 5
Dependent Claim
23 words
The method of claim 1, wherein a shape of each of said plurality of first regions is indeterminate prior to said image-segmenting step.
Claim 6
Dependent Claim
35 words
The method of claim 1, wherein a shape of each of said plurality of first regions is dependent upon the picture element information for each of the plurality of picture elements in said current picture.
Claim 7
Independent Claim
222 words
A system for processing a sequence of motion pictures, each motion picture comprising a plurality of picture elements, said system comprising: picture element information determining means for determining picture element information for each picture element in a current picture of said sequence of motion pictures, said picture element information including a Plurality of components comprising a signal value of said each picture element, a coordinate position of said each picture element, and a motion estimation vector of said each picture element, said motion estimation vector being determined based on a position of said picture element in said current picture and a position of at least one corresponding picture element in a previous picture to said current picture; image segmenter means for image-segmenting said current picture in said sequence of motion pictures into a plurality of first regions, wherein the image-segmenting is dependent on each component said picture element information for each of said plurality of picture elements of said current picture; and motion estimator means for determining for each of said plurality of first regions a corresponding second region in a previous picture to said current picture in said sequence of motion pictures, and for estimating a relative motion between each of said plurality of first regions and said corresponding second region to determine a motion vector representative of said relative motion.
Claim 8
