An Improved MB-LBP Defect Recognition Approach for the Surface of Steel Plates

open access: yesApplied Sciences, 2019
The detection of surface defects is very important for the quality improvement of steel plates. In actual production, as the steel plate production line runs faster, the steel surface defect detection algorithm is required to meet the requirements of ...

Using UAS Hyperspatial RGB Imagery for Identifying Beach Zones along the South Texas Coast

open access: yesRemote Sensing, 2017
Shoreline information is fundamental for understanding coastal dynamics and for implementing environmental policy. The analysis of shoreline variability usually uses a group of shoreline indicators visibly discernible in coastal imagery, such as the ...

Efficient Evaluation of the Number of False Alarm Criterion

open access: yes, 2018
This paper proposes a method for computing efficiently the significance of a parametric pattern inside a binary image. On the one hand, a-contrario strategies avoid the user involvement for tuning detection thresholds, and allow one to account fairly for

Learning Correspondence Structures for Person Re-identification

open access: yes, 2017
This paper addresses the problem of handling spatial misalignments due to camera-view changes or human-pose variations in person re-identification. We first introduce a boosting-based approach to learn a correspondence structure which indicates the patch-

Photolithographic fabrication method of computer-generated holographic interferograms [PDF]

open access: yes, 1989
We consider the fabrication of high-quality interferogram-type diffractive optical elements with conventional photolithographic techniques and compare the results with those achievable with electron-beam lithography. The fringes associated with the phase

Segmentation of laterally symmetric overlapping objects: application to images of collective animal behaviour

open access: yes, 2019
Video analysis is currently the main non-intrusive method for the study of collective behavior. However, 3D-to-2D projection leads to overlapping of observed objects. The situation is further complicated by the absence of stall shapes for the majority of

RGB-D face recognition using LBP with suitable feature dimension of depth image

open access: yesIET Cyber-Physical Systems, 2019
This study proposes a robust method for the face recognition from low-resolution red, green, and blue-depth (RGB-D) cameras acquired images which have a wide range of variations in head pose, illumination, facial expression, and occlusion in some cases ...

Disappearance of Spurious States in Analog Associative Memories

open access: yes, 2003
We show that symmetric n-mixture states, when they exist, are almost never stable in autoassociative networks with threshold-linear units. Only with a binary coding scheme we could find a limited region of the parameter space in which either 2-mixtures ...

The Brownian limit of separable permutations [PDF]

open access: yes, 2017
We study random uniform permutations in an important class of pattern-avoiding permutations: the separable permutations. We describe the asymptotics of the number of occurrences of any fixed given pattern in such a random permutation in terms of the ...

Sparse Radial Sampling LBP for Writer Identification

open access: yes, 2015
In this paper we present the use of Sparse Radial Sampling Local Binary Patterns, a variant of Local Binary Patterns (LBP) for text-as-texture classification.
