On the estimation of geodesic paths on sampled manifolds under random projections
In this paper, we focus on the use of random projections as a dimensionality reduction tool for sampled manifolds in highdimensional Euclidean spaces. We show that geodesic paths ...

Level set curve evolution partitioning of polarimetric images
We investigate a method of segmentation of multichannel polarimetric images, such as in laser illuminated or synthetic aperture radar, into a given but arbitrary number of regions...

Blood vessel segmentation using moving-window robust automatic threshold selection
Two moving-window methods, using either flat or Gaussian weighted windows, for local thresholding with Robust Automatic Threshold Selection are developed. The results show that fa...

Perceptual watermarking of non i.i.d. signals based on wide spread spectrum using side information
The theoretical foundations of data hiding have been revealed by formulating the problem as message communication over a noisy channel, i.e. the host document. In light of this de...
