Abstract:
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; and providing an image significance by computing a significance of each pixel in the image to resize. An original spatial domain (Ω) of the significance image is extracted. A transformation Tθ, parameterized as an interpolating spline by a set of control points, is provided from Ω to a resized spatial domain Ω′; subdividing Ω into cells, each cell being defined by a subset of control points of the set. For each cell, a weighted average of the significance of the pixels in the cell is computed, the weighted average being computed using the interpolating spline. The cells of Ω are deformed by displacing one or more control points of the cells having a lesser weighted average. The transformation Tθ over a spatial domain of the image I is computed using the displaced one or more control points. A resized image J is computed by applying the computed transformation Tθ to the spatial domain of the image I to resize.
