Curvelets and Wave Atoms for Mirror-Extended Images
Curvelets Wave Atoms Mirror-Extended Images
2015/7/15
We present variants of both the digital curvelet transform, and the digital wave atom transform, which handle the image boundaries by mirror extension. Previous versions of these transforms treated im...
A RVR-based Method for Bias Field Estimation in Brain Magnetic Resonance Images Segmentation
A RVR-based Method Bias Field Estimation Brain Magnetic Resonance Images Segmentation
2018/4/19
Abstract— This paper presents a relevance vector regression (RVR) based parametric approach to the bias field estimation in brain magnetic resonance (MR) image segmentation. Segmentation is a very imp...
Multiscale flat norm signatures for shapes and images
Multiscale flat norm signatures shapes and images
2010/9/21
In this paper we begin to explore the application of the multiscale flat norm introduced in Morgan and Vixie [13] to shape and image analysis. In particular, we look at the use of the multiscale flat ...
Global generation of the direct images of relative pluricanonical systems
Global generation direct images of relative pluricanonical systems
2011/1/18
In this article, using the plurisubharmonic variation property of canonical measures (cf. [T7]), we prove that for an algebraic fiber space f : X −! Y ,fOX(mKX/Y ) is globally generated on the ...
Hausdorff and packing dimensions of the images of random fields
Hausdorff packing dimensions the images of random fields
2010/11/24
Let $X=\{X(t),t\in\mathbb{R}^N\}$ be a random field with values in $\mathbb{R}^d$. For any finite Borel measure $\mu$ and analytic set $E\subset\mathbb{R}^N$, the Hausdorff and packing dimensions of t...

2010/12/8
We describe an algorithm for distinguishing hyperbolic compo-nents in the parameter space of quadratic rational maps with a periodic critical point. We then illustrate computer images of the hyperboli...
On the computation of the Hausdorff metric between digitised images in three dimensions
fractals Hausdorff metric image comparison
2010/9/14
Efficient and fast solutions to the problem of computing the Hausdorff metric between two arbitrary grey-scale, digitised images are considered. The more efficient of the techniques proposed here cons...
Encryption-compression of images based on FMT and AES algorithm
Encryption the multi-scale base of Faber-Schauder Encryption-compression
2010/9/16
The use of the data-processing networks, for the transmission and the transfer of the data, must satisfy two objectives which are: the reduction of the volume of information to free, the maximum possi...
In this work, we experiment with the choice of reference images, in the process of video compression, by using only the intra and predicted images extracted from sequences. For intra and predicted ima...
We will show that, consistently, every uncountable set can be continuously mapped onto a non measure zero set, while there exists an uncountable set whose all continuous images into a Polish space are...
Lattice parameters from direct-space images at two tilts
Lattice parameters direct-space images
2010/11/2
Lattices in three dimensions are oft studied from the ``reciprocal space'' perspective of diffraction. Today, the full lattice of a crystal can often be inferred from direct-space information about t...
