A blind watermarking technique for multiple watermarks
We propose a blind watermarking technique to embed multiple watermarks simultaneously. It allows the use of correlated key to embed multiple watermarks. A dual-key system is used ...

3D Model Retrieval Based on 3D Discrete Cosine Transform
: The content-based retrieval systems for 3D models on the Web become necessary since digital databases of 3D objects are growing. In this paper, we propose a new method to describ...

A SIMD Vectorizing Compiler for Digital Signal Processing Algorithms
Short vector SIMD instructions on recent microprocessors, such as SSE on Pentium III and 4, speed up code but are a major challenge to software developers. We present a compiler t...
