Abstract
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 five main steps: Partition projection, Image modeling, Image simplification, Marker extraction and Decision. New techniques are proposed to improve the Partition projection in order to enable better temporal stability. Such techniques involve the definition of a new cost function for the watershed algorithm that accounts for the relative position between initial markers and candidate pixels.
