Reconstruction of local features for facial video compression
We suggest a feature based facial image reconstruction technique. The encoding technique utilizes the affine structure of the face to capture the global facial motion. The structure information is transmitted only once at ...
An integrated approach for range image segmentation and representation
This paper proposes an efficient method for the segmentation and representation of 3D rigid, solid objects from its range images using differential invariants derived from classical differential geometry. An efficient ...
Model based object recognition — the role of affine invariants
This paper proposes an efficient method to recognize rigid flat objects from its intensity images which are assumed to be arbitrarily positioned in space. The task of the recognition method is to find instances of known ...
Region-based image retrieval using integrated color, shape, and location index
A technique to retrieve images by region matching using a combined feature index based on color, shape, and location is presented within the framework of MPEG-7. Dominant regions within each image are indexed using integrated ...
Affine-structure-based facial image encoding
A real-time algorithm for affine-structure-based video compression for facial images is presented. The face undergoing motion is segmented and triangulated to yield a set of control points. The set of control points generated ...
