Althogh the diversity of mobile devices brings in image retargeting technique to effectively display images on various screens, no existing image retargeting method can handle all images well. In this paper, we propose a novel approach to select suitable image retargeting methods solely based on original image characteristic, which can obtain acceptable selection accuracy with low computation c...

Active contours are used extensively in vision for more than two decades, primarily for applications such as image segmentation and object detection. The vast majority of active contours models make use of closed curves and the few that employ open curves rely on either fixed boundary conditions or no boundary conditions at all. In this paper we discuss a new class of open active contours with ...

The major contribution of this paper is the use and define energy functions that study the visual features, such as image gradients, to preserve the important content of an image. Classical methods of resizing or cropping images have limitations in the sense that they distort or cut important regions of an image. By applying higher energy around pixels containing faces and lower energy for back...

Image retargeting aims to resize an image to one with a prescribed aspect ratio. Simple scaling inevitably introduces unnatural geometric distortions on the important content of the image. In this paper, we propose a simple and yet effective method to resize an image, which preserves the geometry of the important content, using the Beltrami representation. Our algorithm allows users to interact...

In recent years, the development and demand of multimedia product grows progressively fast, contributing to inadequate bandwidth of network and memory storage for device. Therefore, the term called compression becomes more and more significant. There are many image compression methods which compress the image as a whole and not considering the device storage and resources. Therefore, content aw...
