In this paper, we present a simple method to almost quadruple the spatial resolution of aliased images. From a set of four low resolution, undersampled and shifted images, a new i...
The universal scalability, which integrates different types of scalabilities and consequently provides a large scaling range for each codec parameter, is of high interests to the ...
This paper presents an approach to capture visual appearance of a real environment such as an interior of a room. We propose the method for generating arbitrary viewpoint images b...
In this paper, we propose a novel authentication method for digital images that achieves fine authenticating granularity (e.g., block-level granularity). Its appealing flexibility ...
In this paper, we propose a bitstream switching scheme for progressive fine granularity scalable (PFGS) video coding that aims to improve the streaming performance of the scalable...
In this paper, we propose a content based video categorizing method focusing broadcasted sports videos using camera motion parameters. We define two new features in the proposed m...
The paper addresses the problem of distinguishing between pornographic and non-pornographic photographs, for the design of semantic filters for the web. Both, decision forests of ...
