On Knotted Necklaces of Pearls
A knotted necklace of pearls is a necklace whose string forms a nontrivial knot. We assume that all pearls are balls of the same size, and any two consecutive pearls in a knotted necklace are tangent to each other. How many pearls are necessary to make ...
Low-complexity and low-memory entropy coder for image compression
A low-complexity and low-memory entropy coder (LLEC) is proposed for image compression. The two key elements in the LLEC are zerotree coding and Golomb-Rice (1966, 1991) codes. Zerotree coding exploits the zerotree structure of transformed coefficients ...
New CAVLC design for lossless intra coding
ICIP'09: Proceedings of the 16th IEEE international conference on Image processingThe context-based adaptive variable length coder (CAVLC) in H.264/AVC is not appropriate for lossless video coding because it was designed for lossy video coding. Since statistical characteristics of residual data in lossy and lossless coding are quite ...
