A Subpixel Registration Algorithm for Low PSNR Images
Song Feng, Linhua Deng, Guofeng Shu +3
This paper presents a fast algorithm for obtaining high-accuracy subpixel translation of low PSNR images. Instead of locating the maximum point on the upsampled images or fitting t…
Objective Image Quality Assessment for High Resolution Photospheric Images by Median Filter Gradient Similarity
Hui Deng, Dandan Zhang, Tianyu Wang +6
All next generation ground-based and space-based solar telescopes require a good quality assessment metric in order to evaluate their imaging performance. In this paper, a new imag…
NVST data archiving system based on fastbit nosql database
Yingbo Liu, Feng Wang, Kaifan Ji +3
The New Vacuum Solar Telescope (NVST) is a 1-meter vacuum solar telescope that aims to observe the fine structures of active regions on the Sun. The main tasks of the NVST are high…
Low-cost high performance distributed data storage for multi-channel observations
Ying-bo Liu, Feng Wang, Hui Deng +5
The New Vacuum Solar Telescope (NVST) is a 1-m solar telescope that aims to observe the fine structures in both the photosphere and the chromosphere of the Sun. The observational d…
Distributed Data-Processing Pipeline for Mingantu Ultrawide Spectral Radioheliograph
F. Wang, Y. Mei, H. Deng +8
The Chinese Spectral RadioHeliograph (CSRH) is a synthetic aperture radio interferometer built in Inner Mongolia, China. As a solar-dedicated interferometric array, CSRH is capable…
On the relationship between G-band bright point dynamics and their magnetic field strengths
Yunfei Yang, Qiang Li, Kaifan Ji +4
G-band bright points (GBPs) are regarded as good manifestations of magnetic flux concentrations. We aim to investigate the relationship between the dynamic properties of GBPs and t…
Investigation of intergranular bright points from the New Vacuum Solar Telescope
Kai-Fan Ji, Jian-ping Xiong, Yong-yuan Xiang +4
Six high-resolution TiO-band image sequences from the New Vacuum Solar Telescope (NVST) are used to investigate the properties of intergranular bright points (igBPs). We detect the…
Investigation of Umbral Dots with the New Vacuum Solar Telescope
Kaifan Ji, Xia Jiang, Song Feng +3
Umbral dots (UDs) are small isolated brightenings observed in sunspot umbrae. They are convective phenomena existing inside umbrae. UDs are usually divided into central UDs (CUDs)…
Characterising motion types of G-band bright points in the quiet Sun
Yun-Fei Yang, Hui-Xue Qu, Kai-Fan Ji +4
We study the motions of G band bright points (GBPs) in the quiet Sun to obtain the characteristics of different motion types. A high resolution image sequence taken with the Hinode…
