| Research Abstract |
This study focuses on image coding and digital watermarking via cyclic signal processing. Main contributions of this work are three-fold : 1) an image compression technique based on a cosine-modulated filter bank, 2) a blind watermarking technique of three dimensional meshes, and 3) a quadtree-based algorithm for image coding. I presented the aforementioned approaches and demonstrated their validity.
