System using parallel coordinates for automated line detection in noisy images
TLDR
In this paper, a line detection method using line neighborhoods and a parallel coordinate transformation is proposed to accommodate the uncertainty in line detection arising from image noise, where line neighborhoods are used to transform Cartesian coordinate image plane line segments to points in a bounded and nonambiguous region of the parallel coordinate transform plane.Abstract:
A system for detecting lines in images using line neighborhoods and a parallel coordinate transformation. The process introduces the concept of line neighborhoods to accommodate the uncertainty in line detection arising from image noise. Because line neighborhoods in Cartesian coordinates have ambiguous and unbounded regions and always overlap one another, a parallel coordinate transform is used to transform Cartesian coordinate image plane line segments to points in a bounded and nonambiguous region of the parallel coordinate transform plane. Line detection then becomes a simple problem of detecting point clusters in the parallel coordinate transform plane.read more

Programs and methods for the display, analysis and manipulation of multi-dimensional data implemented on a computer
TL;DR: In this article, a set of visualization routines designed to improve display, visualization and manipulation of multi-dimensional data are presented, combining 2D and 3D renderings with domain selecting criteria and stacking criteria with line segments connecting variable values between records in a given dataset or between corresponding variable values in records of related datasets.

Discussion: Interacting with parallel coordinates
Harri Siirtola,Kari-Jouko Räihä +1 more
TL;DR: A survey of current interaction techniques for parallel coordinate browsers and compares them to the visualization design guidelines in the literature and shows that although the subjects had doubts about the general usefulness of the parallel coordinate technique, they could perform the tasks more efficiently with a parallel coordinate browser than with their familiar query language interface.

Fatih Porikli,Jie Shao +1 more
TL;DR: In this article, a method detects roads in an aerial image of ground topology by determining low-level features, such as intensities and gradients, for each pixel in the aerial image, determining middle level features such as an orientation of each pixel from the low level features, and determining high level features from the middle level feature.

TL;DR: In this article, a detection scheme identifies portions of the image having a signal-to-noise ratio greater than a given threshold, and a classification scheme is applied to each such portion to generate fractal feature values associated therewith in order to classify the portion as a target or non-target.

Preprocessing means for use in a pattern classification system
TL;DR: In this article, a method for preprocessing reference feature vectors representing patterns in order to form, for each selected pattern class, collections of regions is presented, which are used to classify a feature vector representing an unknown pattern as belonging to a pattern class and assign a confidence value indicating the relative confidence associated with the possibility that this unknown input pattern belongs to the pattern class.
