Image classification for detection of winter grapevine buds in natural conditions using scale-invariant features transform, bag of features and support vector machines
(Elsevier, 2017-04)
In viticulture, there are several applications where bud detection in vineyard images is a necessary task, susceptible of being automated through the use of computer vision methods. A common and effective family of visual ...
NDT flaw mapping of steel surfaces by continuous magnetic Barkhausen noise: Volumetric flaw detection case
(ELSEVIER SCI LTD, 2009)
This paper reports the use of a non-destructive, continuous magnetic Barkhausen noise (CMBN) technique to investigate the size and thickness of volumetric defects, in a 1070 steel. The magnetic behavior of the used probe ...

Feature detection with a constant FAR in sparse 3-D point cloud data
(IEEE, 2020)
The detection of markers or reflectors within point cloud data (PCD) is often used for 3-D scan registration, mapping, and 3-D environmental modeling. However, the reliable detection of such artifacts is diminished when ...

Efficient Approach for OS-CFAR 2D Technique Using Distributive Histograms and Breakdown Point Optimal Concept applied to Acoustic Images
(Institution of Engineering and Technology, 2019-12)
In this work, a new approach to improve the algorithmic efficiency of the Order Statistic-Constant False Alarm Rate (OS-CFAR) applied in two dimensions (2D) is presented. OS-CFAR is widely used in radar technology for ...
