  • Affine-structure-based facial image encoding 

    Chatterjee, S; Banerjee, S; Biswas, K K (1999)
    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 ...
  • An integrated approach for range image segmentation and representation 

    Bose, S K; Biswas, K K; Gupta, S K (1996)
    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 

    Bose, S K; Biswas, K K; Gupta, S K. (1996)
    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 ...
  • Reconstruction of local features for facial video compression 

    Chatterjee, S; Banerjee, S; Biswas, K K (2000)
    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 ...
  • Region-based image retrieval using integrated color, shape, and location index 

    Prasad, B G; Biswas, K K; Gupta, S K (2004)
    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 ...
