Aliasing artifacts in images are visually very disturbing. Therefore, most imaging devices apply a low-pass filter before sampling. This removes all aliasing from the image, but i...

Distributed Video Coding (DVC) is a coding paradigm that gives the decoder the task to exploit the source statistics to achieve efficient compression. Current approaches to DVC rel...
Side estimation plays an important role in Wyner-Ziv video coding. In this paper, we examine the use of two conventional motion search methods to improve side estimation. Unlike m...
We address the problem of segmenting multiple similar objects by optimizing a Chan-Vese-like [1] functional with respect to a mixture of level set functions. We solve the variatio...
An embedded, block-based, wavelet transform coding algorithm of low complexity is proposed. Three-Dimensional Set Partitioned Embedded bloCK(3D-SPECK) efficiently encodes hyperspe...
In this paper we present an approach for lip motion analysis that can be used in conjunction with a person authentication system based on face recognition, to avoid attacks on the...

Video transmission over networks is getting increasingly important, thus upcoming network types like Mobile Ad-Hoc Networks (MANETs) can also become a suitable platform for exchan...
This paper proposes a robust real-time, scalable and modular Field Programmable Gate Array (FPGA) based implementation of a spatiotemporal segmentation of video objects. The goal ...
In natural images, luminance changes occur both on object contours and on textures. Often, the latter are stronger than the former, thus standard edge detectors fail in isolating ...

For the first time, we compute modulation domain features for infrared targets and backgrounds, including dominant modulations that characterize the local texture contrast, orient...
