When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording the diffraction patterns formed by shining a laser beam through it. At the ...

Abstract: This paper introduces a design method for densergraph-frequency graph Fourier frames (DGFFs) to enhance graph signal processing and analysis. The graph Fourier transform (GFT) enables us to ...

Using concepts students are already familiar with — like how bottles vibrate — can serve as a helpful anchor for more complex topics.

FTIR-7600 is a single-beam Fourier-transform infrared spectrometer with fast scan speed and high accuracy. This instrument is operated by a PC with user friendly software and a comprehensive manual.

Abstract: Event camera calibration plays an irreplaceable role in event camera-based visual applications. Event cameras report per-pixel brightness changes as a stream of asynchronous events, making ...
