Relative Heading Estimation for Pedestrians Based on the Gravity Vector [PDF]

open access: yes, 2021
Inertial navigation of pedestrians carrying a smart device is a core component of many indoor positioning systems. While infrastructure-based solutions typically depend on an installation of dedicated hardware, inertial navigation depends only on sensors

Stature estimation using head circumference

open access: yesJournal of Advanced Pharmaceutical Technology & Research, 2022
Stature is an essential measurement in anthropometry that resolves individual representation of the body. Forensic determination is the resolution of origin, sex, and natural height. Many previous study has been done on estimation of height using various measurements of teeth and skull. The aim of this study was to estimate stature

Indoor Heading Direction Estimation Using Rf Signals [PDF]

open access: yes, 2020
Heading direction information is crucial to many ubiquitous computing applications. The main stream has been resorting to inertial sensors, such as accelerometer, gyroscope and magnetometer, which suffer from severe accumulative errors or large ...

UAV Remote Sensing Estimation of Rice Yield Based on Adaptive Spectral Endmembers and Bilinear Mixing Model

open access: yesRemote Sensing, 2021
The accurate estimation of rice yield using remote sensing (RS) technology is crucially important for agricultural decision-making. The rice yield estimation model based on the vegetation index (VI) is commonly used when working with RS methods, however,

Direction specific biases in human visual and vestibular heading perception. [PDF]

open access: yesPLoS ONE, 2012
Heading direction is determined from visual and vestibular cues. Both sensory modalities have been shown to have better direction discrimination for headings near straight ahead.

Head pose estimation by regression algorithm

open access: yesPattern Recognition Letters, 2020
Abstract Head pose estimation is a very in-depth topic in the context of biometric recognition, especially in video surveillance, because the rotation of the head can affect the recognition of some features of the face. Being able to recognize in advance the pose of the head in pitch, yaw and roll enable frontalization or the extraction of a frame in

Estimating Head Motion from Mr-Images

open access: yes2023 IEEE 20th International Symposium on Biomedical Imaging (ISBI), 2023
Head motion is an omnipresent confounder of magnetic resonance image (MRI) analyses as it systematically affects morphometric measurements, even when visual quality control is performed. In order to estimate subtle head motion, that remains undetected by experts, we introduce a deep learning method to predict in-scanner head motion directly from T1 ...

Pre-Processing Technique for Compass-less Madgwick in Heading Estimation for Industry 4.0 [PDF]

open access: yes, 2020
The high quality of heading orientation is a key factor to monitor the industrial robot arms in the Industry 4.0. The paper proposes a new algorithm ‘No Motion No Integration’ (NMNI) to enhance the gyroscope performance via signal processing and ...

PDR algorithm for precise positioning of underground personnel based on LSTM personalized step size estimation

open access: yesGong-kuang zidonghua, 2022
The traditional pedestrian dead reckoning (PDR) algorithm has low positioning precision due to the accumulated errors of step size and heading, which can not meet the requirements of precise positioning of underground personnel.
