1. A method for retargeting an image, comprising:
- determining a total block structure energy of an input image content by a processing unit;
determining a compressibility rate of said input image content based on said total block structure energy by said processing unit;
determining an optimal scaling factor of said input image content by said processing unit; and
warping said input image content by using a new coordinate matrices and uniformly scaling said input image content by said processing to output a target image resolution;
wherein said compressibility rate (rx and ry) of said input image content may be obtained by the following equations;

Abstract
The present invention provides a method for retargeting an image, comprising determining a total block structure energy of an input image content. A compressibility rate of the input image content is determined based on the total block structure energy. An optimal scaling factor of the input image content is obtained. The input image content is warped by using a new coordinate matrices and uniformly scaling the input image content to a target image resolution.
