Benchmark low-mass objects in Moving Groups

EPJ Web of Conferences, 2013
In order to compile a sample of ultracool dwarfs that will serve as benchmarks for testing theoretical formation and evolutionary models, we selected low-mass cool (>M7) objects that are potentially members of five known young Moving Groups in the solar ...

Speed Estimation of Multiple Moving Objects from a Moving UAV Platform

ISPRS International Journal of Geo-Information, 2019
Speed detection of a moving object using an optical camera has always been an important subject to study in computer vision. This is one of the key components to address in many application areas, such as transportation systems, military and naval ...

DIFFUSION BACKGROUND MODEL FOR MOVING OBJECTS DETECTION [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
In this paper, we propose a new approach for moving objects detection in video surveillance systems. It is based on construction of the regression diffusion maps for the image sequence.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Video Desnowing and Deraining via Saliency and Dual Adaptive Spatiotemporal Filtering

Sensors, 2021
Outdoor vision sensing systems often struggle with poor weather conditions, such as snow and rain, which poses a great challenge to existing video desnowing and deraining methods. In this paper, we propose a novel video desnowing and deraining model that

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

High Dynamic Range Image Deghosting Using Spectral Angle Mapper

Computers, 2019
The generation of high dynamic range (HDR) images in the presence of moving objects results in the appearance of blurred objects. These blurred objects are called ghosts.

Moving objects multi-classification based on information fusion

Journal of King Saud University: Computer and Information Sciences, 2022
This paper aims to present a new model for multi-classification in video surveillance, based on data fusion. First, features are extracted. Then, a pre-classification is conducted using each feature separately.
