Blocking artifacts are a major degradation affecting blockbased video compression. In this paper an adaptively based filter is proposed, whereby the type of filtering to be applie...
This paper proposes a computationally efficient approach of adaptive directional wavelet transform (AD WT). The AD WT is based on lifting implementation of WT, and it is able to t...
Given a scene consisting of objects, ray shooting queries answer with the first object encountered by a given ray, and are used in ray tracing and radiosity for rendering photo-r...
In a traditional streaming system, the field of view (FOV) of an image is limited based on the FOV of the camera. One solution is the use of a pan/tilt camera, yet this is difficu...
This paper presents a new approach to imaging that significantly enhances the dynamic range of a camera. The key idea is to adapt the exposure of each pixel on the image detector,...
