Content-based Image Resizing on Mobile Devices

Content-aware image resizing are effective algorithms that allow to take into account the visual content of images during the resizing process. Despite the technological advances in the context of mobile devices, content-aware image resizing algorithms are still far to be used on a hand held device due to the computational resources needed during the resizing. In this paper we afford this problem employing a method which has linear complexity with respect to the number of lines (rows/columns) to be reduced/augmented. The method has been tested, both qualitatively and quantitatively, on a mobile platform.
