SEGMENTATION OF AN IMAGE

摘要

The invention concerns a method, device and computer program product for segmenting an image in a signal as well as a device for providing a multi-dimensional image. In the device (32) for segmenting an image there is provided a segmenting unit (48) arranged to apply a segmentation scheme to images, and a control unit (44) arranged to divide a present image (I2) in the signal into a number of regions (10), select a limited number of regions, order said segmenting unit to apply said segmentation scheme on said selected regions that provides at least one fresh segment, and provide at least one segment (S) created for a previous image (I1) in the signal to the other regions of the present image. In this way the required computational power is reduced while at the same time providing a balance between the accuracy and temporal consistency requirements for the segmentations.
