Effect of nonstationarities on detrended fluctuation analysis [PDF]

, 2001
Detrended fluctuation analysis (DFA) is a scaling analysis method used to quantify long-range power-law correlations in signals. Many physical and biological signals are ``noisy'', heterogeneous and exhibit different types of nonstationarities, which can

Dual-fisheye lens stitching for 360-degree imaging

, 2017
Dual-fisheye lens cameras have been increasingly used for 360-degree immersive imaging. However, the limited overlapping field of views and misalignment between the two lenses give rise to visible discontinuities in the stitching boundaries.

Statistical Analysis of Measurement Processes Using Multi-Physic Instruments: Insights from Stitched Maps

Metrology
Stitching methods allow one to measure a wider surface without the loss of resolution. The observation of small details with a better topographical representation is thus possible.
