Temporal Stability in Sequence Segmentation Using the Watershed Algorithm
نویسنده
چکیده
The necessity of temporal stability in partition sequences for segmentation-based video coding techniques is stated. A time recursive segmentation approach is analyzed under this scope. The structure of this approach has ve main steps: Partition projection, Image modeling, Image simpliication, Marker extraction and Decision. New techniques are proposed to improve the Partition projection in order to enable better temporal stability. Such techniques involve the deenition of a new cost function for the watershed algorithm that accounts for the relative position between initial markers and candidate pixels.

Video Object Segmentation Using Spatio-Temporal Information and Marked-Watershed Operation
In this paper, we propose a video object segmentation algorithm based on spatio-temporal information and marked-watershed for extracting the moving objects from a video sequence. The algorithm begins with difference image between two adjacent frames and, using the Canny operator on the difference image, determines the initial edge mask for the object in motion. Morphological techniques are appl...

متن کاملPredictive watershed: a fast watershed algorithm for video segmentation
Watershed transform is a key operator in video segmentation algorithms. However, the computation load of watershed transform is too large for real-time applications. In this paper, a new fast watershed algorithm, named P-Watershed, for image sequence segmentation is proposed. By utilizing the temporal coherence property of the video signal, this algorithm updates watersheds instead of searching...
