    VolQD: Direct Volume Rendering of Multi-million Atom Quantum Dot Simulations
    Download  www.ecn.purdue.edu
    In this work we present a hardware-accelerated direct volume rendering system for visualizing multivariate wave functions in semiconducting quantum dot (QD) simulations. The simul...

    3-D Surface Segmentation of Free-Form Objects Using Implicit Algebraic Surfaces
    Download  www.aprs.org.au
    This paper describes a new technique for free-form object segmentation from a single arbitrary-viewed range image. The aim is to derive a surface description of objects that may va...

    On the use of discrete Pascal transform in hiding data in images
    Download  dsmc2.eap.gr
    The Discrete Pascal Transform (DPT) has been proved remarkably useful for edge detection, filter design, discrete-time signal interpolation and data hiding. In the present work a n...

    Image Coding Using Dual-Tree Discrete Wavelet Transform
    Download  media.au.tsinghua.edu.cn
    In this paper, we explore the application of 2-D dual-tree discrete wavelet transform (DDWT), which is a directional and redundant transform, for image coding. Three methods for sp...
