Visual saliency is an important cue in human visual system to detect salient objects in natural scenes. It has attracted a lot of research focus in computer vision, and has been widely used in many applications including image retrieval, object recognition, image segmentation, and etc. However, the accuracy of salient object detection model remains a(More)
Saliency computational model with active environment perception can be useful for many applications including image segmentation, image compression, image retrieval, and etc. Conventional saliency computational models rely on handcrafted low level features, such as color or contrast. These models face great difficulties in low lighting scenarios, due to the(More)
Saliency computational model with active environment perception can substantially facilitate a wide range of applications. Conventional saliency computational models primarily rely on hand-crafted low level image features, such as color or contrast. However, they may face great challenges in low lighting scenario, due to the lack of well-defined feature to(More)
Human can quickly and effortlessly focus on a few most interesting points in an image. Different observers tend to have the same fixations towards the same scene. In order to predict observer's fixations, eye gaze information can be used to reveal human attention and interest. This paper presents a real-time eye gaze tracking system.

Salient object detection model with active environment perception can substantially facilitate a wide range of applications. Conventional models primarily rely on handcrafted low-level image features or high-level features. However, these models may face great challenges in low-lighting scenario, due to the lack of well-defined features to represent(More)
With the development of ubiquitous networks, the personalization of ubiquitous services demand different kinds of heterogeneous devices to cooperate with each other. However, limited network resources and device capabilities will cause allocation conflict of multi-services utilities for multi-users' requests in ubiquitous stub environments. Thus, when users(More)
With the integration of mobile devices into ubiquitous environments, a wide range of services can be provided by exploiting the resources on heterogeneous devices, especially in MANETs. Because resources on mobile devices are shared out, it is essential to arrange highly-limited resources effectively and reasonably while considering utilities of multi-users(More)
