3d Medical Image Compression Based On Multiplierless Low-complexity Rklt And Shape-adaptive Wavelet Transform
A multiplier-less low complexity reversible integer Karhunen-Lo?ve transform (Low-RKLT) is proposed based on multi-lifting. Conventional methods based on KLT suffer from high comp...

2d-3d Registration Of Deformable Shapes With Manifold Projection
We present an algorithm able to register a known 3D deformable model to a set of 2D matched points extracted from a single image. Unlike previous approaches, the problem is solved...
