A wireless ad hoc network (WANET) is a type of wireless network aimed to be deployed in a
disaster area in order to collect data of patients and improve medical facilities. The WANETs …

Since different regions of a color image generally exhibit different spectral characteristics,
the energy compaction of applying a single spectral transform to all regions is largely …

This work is motivated by the limitations of statistical quality metrics to assess the quality of
images distorted in distinct frequency ranges. Common quality metrics, which basically have …

Quality assessment is of major importance when designing and testing an image/video
coding technique. Compression performances are usually evaluated by means of rate …

When considering color images and more generally multi component images, state of the art
image codecs usually achieve component decorrelation through static color transforms such …

Through the development of medical imaging systems and their integration into a complete
information system, the need for advanced joint coding and network services becomes …

Next generations of still image codecs should not only have to be efficient in terms of
compression ratio, but also propose other functionalities such as scalability, lossy and …

Multi-view video plus depth (MVD) data is a set of multiple sequences capturing the same
scene at different viewpoints, with their associated per-pixel depth value. Overcoming this …

Implementing an algorithm to hardware platforms is generally not an easy task. The
algorithm, typically described in a high-level specification language, must be translated to a …

Embedded image codecs have generally strong constraints in terms of speed, latency and
complexity. We introduce in this paper a dedicated coder implementation of the LAR coding …
