Line detection algorithm

Proceedings of 13th International Conference on Pattern Recognition, 1996
In this paper, a simple and efficient approach in the line segment detection algorithm, which employs the properties of digital line segment, is proposed. In discrete domain, a continuous line can be considered as combination of sets of pattern in the quantized direction of edge pixels (i.e.

Detection of lines, line junctions and line terminations

International Journal of Remote Sensing, 2004
This paper describes an optimal line detector for the one-dimensional case which is derived from Canny's criteria, and an efficient approach for the detection of line junctions and line terminations. The line detector is extended to the two-dimensional case by operating separately in the x and y directions. An efficient implementation using an infinite

DMSA Line (intrusion detection line sensor)

Proceedings. Institute of Electrical and Electronics Engineers 1988 International Carnahan Conference on Security Technology, Crime Countermeasures, 2003
A description is given of DMSA Line, a dual, magnetically coupled, slow propagation and attenuating line, which is the first practical transportable intrusion-detection line sensor. It is designed to be rolled out on the surface of the terrain to protect up to 150 m of perimeter.

On Models for Line Detection

IEEE Transactions on Systems, Man, and Cybernetics, 1976
Several models for line detection in noise are discussed, based on models for the ``simple'' and ``complex'' cells that have been found in the visual cortex. The possibility of obtaining experimental evidence for deciding among the models is briefly considered.

The Detection of Line Segments

Perception, 1977
Many simple cells of the visual cortex have long narrow receptive fields, which are strongly excited by lines oriented along their long axis. In the present psychophysical analysis, we assume that there are similar independent ‘subunits’ which contribute, by probability summation, to the detection of a line.

Asymmetries in preattentive line detection

Vision Research, 1994
We tested the relative contribution of absolute orientation and collinearity to asymmetries in preattentive line detection. Subjects reported the location of a single line that was tilted by 16 deg against the orientation of the background lines. Perceptual pop-out strength was quantified as the threshold presentation time to correctly locate the ...

Line Detection Algorithms

1995
The edge elements detected by the algorithms in Chapter 13 and Chapter 21 will now be connected to lines. This is called contour or line following.

Moment-preserving line detection

Pattern Recognition, 1988
Abstract A new method for line detection in two-dimensional image data is presented. Based on the moment-preserving principle, the method is developed to estimate line location and width to the subpixel accuracy within a circular mask. Experimental results are given to show the effectiveness of the proposed line detector.
