Classification: G06T,H04N

Abstract:
A computer-usable medium storing computer-readable instructions for causing a processor in a computer graphic apparatus to process signals defining current frame pixel data for a frame of interest, reference frame pixel data and a reference frame segmentation in order to produce a desired consistent segmentation for the current frame, the instructions comprising instructions for causing the processor to:a) calculate motion estimation information from the current frame pixel data and the reference frame pixel data to represent spatial transformations occurring between said frames; b) use said motion estimation information and the reference frame segmentation data to obtain a predicted current frame segmentation; c) use said motion estimation information and the reference frame pixel data to obtain a predicted current frame pixel data; d) identify incorrectly predicted current frame pixel data by comparison of the received current frame pixel data and the predicted current frame pixel data; and e) modify the predicted current frame segmentation for the identified current frame pixel data to obtain the desired consistent segmentation for the current frame.
