An Improved Extrapolation Scheme for Truncated CT Data Using 2D Fourier-Based Helgason-Ludwig Consistency Conditions

open access: yesInternational Journal of Biomedical Imaging, 2017
We improve data extrapolation for truncated computed tomography (CT) projections by using Helgason-Ludwig (HL) consistency conditions that mathematically describe the overlap of information between projections. First, we theoretically derive a 2D Fourier

Image-Dehazing Method Based on the Fusion Coding of Contours and Colors

open access: yesIEEE Access, 2019
The dehazing of images shot in fog is a hot spot in the study of computer vision. Unlike dehazing methods, which use an atmospheric scattering model, the method proposed here is based on fusion coding of contours and colors.

Deep Semantic Clustering by Partition Confidence Maximisation [PDF]

open access: yes, 2020
By simultaneously learning visual features and data grouping, deep clustering has shown impressive ability to deal with unsupervised learning for structure analysis of high-dimensional visual data. Existing deep clustering methods typically rely on local

A robust autoassociative memory with coupled networks of Kuramoto-type oscillators [PDF]

open access: yes, 2016
Uncertain recognition success, unfavorable scaling of connection complexity or dependence on complex external input impair the usefulness of current oscillatory neural networks for pattern recognition or restrict technical realizations to small networks.

ClusterFace: Joint Clustering and Classification for Set-Based Face Recognition [PDF]

open access: yes, 2020
Deep learning technology has enabled successful modeling of complex facial features when high quality images are available. Nonetheless, accurate modeling and recognition of human faces in real world scenarios `on the wild' or under adverse conditions ...

Advanced local motion patterns for macro and micro facial expression recognition [PDF]

open access: yes, 2018
In this paper, we develop a new method that recognizes facial expressions, on the basis of an innovative local motion patterns feature, with three main contributions. The first one is the analysis of the face skin temporal elasticity and face deformations during expression.

Comparison of Fiber-Based Gas Pressure Sensors Using Hollow-Core Photonic Crystal Fibers

open access: yesIEEE Photonics Journal, 2021
A systematic comparison of fiber-based gas pressure sensors using different types of hollow-core photonic crystal fibers (PCFs) is conducted. The sensor was fabricated by splicing a segment of hollow-core silica capillary between a single mode fiber (SMF)

A pattern recognition machine

open access: yesKybernetik, 1968
A new probabilistic learning machine for pattern recognition is described. The machine operates on the basis of random criteria obtained from special pseudorandom generators. The input, particularly versatile due to the use of an image dissector, allows a random scan for which normal television storage pick-up tubes are not suitable.
