CATM-CFAR detector in the receiver of the software defined radar [PDF]

open access: yesScientific Technical Review, 2014
This paper presents a model of the CATM-CFAR detector in the receiver of the software defined radar. The mentioned detector is named cell-averaging-trimmed-mean CFAR. It is a combination of cell-averaging and trimmed mean CFAR.

Clutter elimination for deep clinical optoacoustic imaging using localised vibration tagging (LOVIT) [PDF]

open access: yes, 2013
This paper investigates a novel method which allows clutter elimination in deep optoacoustic imaging. Clutter significantly limits imaging depth in clinical optoacoustic imaging, when irradiation optics and ultrasound detector are integrated in a ...

VALIANT: A Vision‐Authenticity Language Framework Through Integrated Experts and Aligned Numerical‐Textual Descriptors for Citri Reticulatae Pericarpium

open access: yesAdvanced Intelligent Systems, EarlyView.
Visual features, numerical descriptors, and controlled textual attributes extracted from smartphone images of Chenpi are integrated by VALIANT, a tailored multimodal framework for simultaneous storage‐age classification and authenticity verification. The workflow distinguishes genuine products from suspicious standard operating procedure mimics while ...

Real-time clutter reduction in epi-optoacoustic imaging of human volunteers

open access: yes, 2014
Optoacoustic (OA) imaging in combination with diagnostic pulse-echo ultrasound is most flexibly implemented with irradiation optics and acoustic probe integrated in epi-style in a combined probe.

Interpreting How Neural Networks Infer Scatterer Geometry from Echolocation Echoes

open access: yesAdvanced Intelligent Systems, EarlyView.
Neural networks enable echolocation‐based shape classification but remain difficult to interpret due to their black‐box nature. This work presents a feature‐importance metric to uncover the echo regions driving decisions in shape‐specialized networks.

A bayesian approach to adaptive detection in nonhomogeneous environments [PDF]

open access: yes, 2008
We consider the adaptive detection of a signal of interest embedded in colored noise, when the environment is nonhomogeneous, i.e., when the training samples used for adaptation do not share the same covariance matrix as the vector under test. A Bayesian

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

open access: yesThe Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

DSIM: A DisSIMilarity-based image clutter metric for targeting performance

open access: yes, 2013
Previous image clutter metrics were proposed on the thought that clutter was just a perceptual effect, while we identify clutter as both perceptual and cognitive effects.

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

open access: yesThe Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

REVIEW OF RADAR DETECTORS WITH CONSTANT FALSE ALARM RATE

open access: yesTelemática, 2020
Radar detection in environments with high spatial and temporal variability is an issue of great importance. Many efforts are devoted to the development of adaptive techniques that allow robust operation for all possible scenarios.
