Artistic silhouettes: a hybrid approach
We present a new algorithm for rendering silhouette outlines of 3D polygonal meshes with stylized strokes. Rather than use silhouette edges of the model directly as the basis for ...

Estimation of attacker's scale and noise variance for qim-dc watermark embedding
Quantization-based watermarking schemes are vulnerable to amplitude scaling. Therefore, the scaling factor needs to be estimated at the decoder side, such that the received (attac...

Fast and effective characterization of 3D region data
We consider the problem of characterization of spatial region data such as the regions of interest (ROIs) in medical images. We propose a method that efficiently extracts a k-dime...

Rate-distortion Optimization For Automatic Sprite Video Coding Using H.264/avc
Sprite-based video coding offers higher compression efficiency than conventional block-based hybrid video coders. In sprite coding a sequence is divided into a model of its backgr...

Geodesic Evolution Laws---A Level-Set Approach
Motion of curves governed by geometric evolution laws, such as mean curvature flow and surface diffusion, is the basis for many algorithms in image processing. If the images to be ...
