In this paper, we present a new shape-coding approach, which decouples the shape
information into two independent signal data sets; the skeleton and the boundary distance …

The MPEG-4 visual standard is developed to provide users a new level of interaction with
visual contents. It is the first international standard allowing for transmitting arbitrarily shaped …

Existing vertex-based operational rate-distortion (ORD) optimal shape coding algorithms
use a vertex band around the shape boundary as the source of candidate control points …

Two new binary shape-coding techniques that are based on finite automata methods are
proposed. Both contour-based and bitmap-based approaches to shape coding are …

The goal of this thesis is to find a highly efficient algorithm to compress patient monitoring
video. This type of video mainly contains local motion and a large percentage of idle …

This paper presents a concise, robust shape-preserving contour tracing scheme for
efficiently extracting a highly representative one-pixel-width closed contour for the profiles of …

In this paper, we present a motion compensated two-link chain coding technique to
effectively encode 2-D binary shape sequences for object-based video coding. This …

This paper proposes an object-oriented coding method in very low bit-rate channels, using
the motion estimation technique based on multiple frame prediction. In most existing …
