Animation Image Coding

 

 

Advanced Multimedia Systems Lab.

 

 

Our approach for describing/encoding animation images is to decompose inputs to line drawings, homogeneous color regions and remaining textures.  This technique can be applied to narrow band data transmission such as mobile and Internet video applications.

 

Lines and contour of homogeneous color regions are approximated by spline curves whereas residuals are encoded by DCT. This representation can avoid blocking effects and gmosquito noiseh that often appear in the conventional DCT-based approach.
