| 1. A method for retargeting an image, comprising a computer system for performing steps of the method, comprising the steps
of:
segmenting an input image into a plurality of regions, wherein parameters of the segmenting include a spatial radius hs, a color radius hr, and a minimum number of pixels M for each of the plurality of regions;
cutting selected regions from the input image to construct a background image;
scaling the background image to a predetermined size; and
pasting the selected regions into the scaled background image to produce an output image, and further comprising:
constructing an importance map from the input image;
assigning an importance to each of the plurality of regions;
selecting the selected regions as important regions according to the importance map, in which a relative spatial relationship
between the important regions is maintained in the output image.
