This paper makes new contributions in motion detection, object segmentation and trajectory
estimation to create a successful object tracking system. A new efficient motion detection …

Thresholding of video images is a great challenge because of their low spatial resolution
and complex background. We investigate the issue of thresholding these images by …

The current state-of-knowledge and state-of-the-art reasonably enable the construction and
operation of critical systems, be they safety-critical or availability-critical. The situation …

Video quality assessment (VQA) is very important for many video processing applications,
eg, compression, archiving, restoration, and enhancement. An ideal video quality metric …

We address the issue of image sequence analysis jointly in space and time. While typical
approaches to such an analysis consider two image frames at a time, we propose to perform …

Deformation tensor morphometry makes use of the derivatives of spatial transformations
between anatomies, to provide highly localized volumetric maps of relative anatomical size …

Changing lighting conditions cause temporal variations of image intensities and make most
existing motion estimation techniques ineffective. As a solution to this problem, we use …

Motion detection is very important in video surveillance system especially for video
compression, human detection, and behaviour analysis. Various approaches have been …

Medical image segmentation is an important step in 3-D reconstruction, and 3-D
reconstruction from medical images is an important application of computer graphics and …

The new MPEG-4 video coding standard enables content-based functionality by introducing
the video object. It is based on segmentation and tracking of moving objects. A new …
