We describe a framework for multiscale image analysis in which line segments play a role
analogous to the role played by points in wavelet analysis. The framework has five key …

One of the central problems of modern mathematical approximation theory is to approximate
functions, or signals, concisely, with elements from a large candidate set called a dictionary …

We construct detectors for" geometric" objects in noisy data. Examples include a detector for
presence of a line segment of unknown length, position, and orientation in two-dimensional …

Accurate identification of the needle target is crucial for effective epidural anesthesia.
Currently, epidural needle placement is administered by a manual technique, relying on the …

In practical electrocardiogram (ECG) monitoring, there are some challenges in reducing the
data burden and energy costs. Therefore, compressed sensing (CS) which can conduct …

Götz, Druckmüller, and, independently, Brady have defined a discrete Radon transform
(DRT) that sums an image's pixel values along a set of aptly chosen discrete lines, complete …

A series of paper samples was investigated using high-resolution phase-contrast
microtomography at the beamline ID 22 of the European Synchrotron Radiation Facility …

We are given a set of n points that might be uniformly distributed in the unit square [0, 1] ².
We wish to test whether the set, although mostly consisting of uniformly scattered points …

We believe computational science as practiced today suffers from a growing credibility gap-it
is impossible to replicate most of the computational results presented at conferences or …

针对射线检测图像中焊缝和缺陷难于准确检测提取问题, 基于逐级局部化处理,
提出了一种实用的检测方法. 方法充分利用了图像本身已包含的信息, 首先通过条带区域特征 …
