Compressing Bitmap Indexes for Faster Search Operations
In this paper, we study the effects of compression on bitmap indexes. The main operations on the bitmaps during query processing are bitwise logical operations such as AND, OR, N...

Bit-plane watermarking for zerotree-coded images
In this paper, we develop a robust bit-plane watermarking technique based on zerotree coding. A robust watermark is an imperceptible but indelible code that can be used for owners...

Color Data Coding for Three-Dimensional Mesh Models Considering Connectivity and Geometry Information
In this paper, we propose a new predictive coding scheme for color data of three-dimensional (3-D) mesh models. We exploit connectivity and geometry information to improve coding ...
