The invention notably relates to computer-implemented method for resizing an image I. The method comprises the steps of:
- providing the image I to resize;
- providing an image significance by computing a significance of each pixel in the image to resize;
- extracting an original spatial domain of the significance image;
- providing a transformation T ¸ , parameterized as an interpolating spline by a set of control points, from © to a resized spatial domain ©';
- subdividing © into cells, each cell being defined by a subset of control points of the set;
- computing, for each cell, a weighted average of the significance of the pixels in the cell, the weighted average being computed using the interpolating spline;
- deforming the cells of © by displacing one or more control points of the cells having a lesser weighted average;
- computing the transformation T ¸ over a spatial domain of the image I using the displaced one or more control points; and
- computing a resized image J by applying the computed transformation T ¸ to the spatial domain of the image I to resize. |
