Interactive Boundary Detection for Automatic Definition of 2D Opacity Transfer Function
In computer assisted diagnostics nowadays, high-value 3-D visualization intake a supporting role to the traditional 2-D slice wise visualization. 3-D visualization may create intui...

Automatic Detection and Segmentation of Ground Glass Opacity Nodules
Ground Glass Opacity (GGO) is defined as hazy increased attenuation within a lung that is not associated with obscured underlying vessels. Since pure (nonsolid) or mixed (partially...

Tensor Splats: Visualising Tensor Fields by Texture Mapped Volume Rendering
Abstract. We describe a new method for visualising tensor fields using a textured mapped volume rendering approach, tensor-splatting. We use an image order method to calculate the ...

Rotation, scaling, and translation-invariant multi-bit watermarking based on log-polar mapping and discrete Fourier transform
This paper proposes an RST-invariant multi-bit watermarking system based on LPM and DFT. This system embeds the watermark in a rotation and translation invariant domain obtained b...
