360-Degree Panorama Generation from Few Unregistered NFoV Images
Jionghao Wang, Ziyu Chen, Jun Ling +2
360 panoramas are extensively utilized as environmental light sources in computer graphics. However, capturing a 360 180 panorama poses challenges…
SpecNet2: Orthogonalization-free spectral embedding by neural networks
Ziyu Chen, Yingzhou Li, Xiuyuan Cheng
Spectral methods which represent data points by eigenvectors of kernel matrices or graph Laplacian matrices have been a primary tool in unsupervised data analysis. In many applicat…
Disentangling modes with crossover instantaneous frequencies by synchrosqueezed chirplet transforms, from theory to application
Ziyu Chen, Hau-Tieng Wu
Analysis of signals with oscillatory modes with crossover instantaneous frequencies is a challenging problem in time series analysis. One way to handle this problem is lifting the…
When Ramanujan meets time-frequency analysis in complicated time series analysis
Ziyu Chen, Hau-Tieng Wu
To handle time series with complicated oscillatory structure, we propose a novel time-frequency (TF) analysis tool that fuses the short time Fourier transform (STFT) and periodic t…
