Segmentation of objects in image sequences is very important in many aspects of
multimedia applications. In second-generation image/video coding, images are segmented …

Intelligent video coding (IVC), which dates back to the late 1980s with the concept of
encoding videos with knowledge and semantics, includes visual content compact …

This paper discusses the interest of binary partition trees as a region-oriented image
representation. Binary partition trees concentrate in a compact and structured representation …

Mathematical morphology provides powerful nonlinear operators for a variety of image
processing tasks such as filtering, segmentation, and edge detection. In this paper, we …

This paper presents a technique for unsupervised video segmentation. This technique
consists of two phases: initial segmentation and temporal tracking, similar to a number of …

This paper discusses region-based representations of image and video that are useful for
multimedia services such as those supported by the MPEG-4 and MPEG-7 standards …

Insight into walking behavior is essential for theory and model development describing the
behavior of individual pedestrians. In turn, microscopic pedestrian simulation models can be …

We present a new image segmentation algorithm based on a tree-structured binary MRF
model. The image is recursively segmented in smaller and smaller regions until a stopping …

The optimal exploitation of the information provided by hyperspectral images requires the
development of advanced image-processing tools. This paper proposes the construction …

We present a scheme for interactive video segmentation. A key feature of the system is the
distinction between two levels of segmentation, namely, regions and object segmentation …
