A projection profile-based algorithm for content-aware image resizing

In this paper, a projection profile-based algorithm is proposed for content-aware image resizing. First, an energy map which describes the image important parts is calculated by an image energy function. Then the algorithm uses horizontal and vertical projection profiles of the energy map to gather importance statistics. Thus, different scaling of the image content is extracted. By this way, the discontinuity that usually occurs in the results of seam carving is overcome. Experiments show that the proposed method is capable of yielding some good results.
