Multivariate interpolation | Signal processing
Lanczos filtering and Lanczos resampling are two applications of a mathematical formula. It can be used as a low-pass filter or used to smoothly interpolate the value of a digital signal between its samples. In the latter case it maps each sample of the given signal to a translated and scaled copy of the Lanczos kernel, which is a sinc function windowed by the central lobe of a second, longer, sinc function. The sum of these translated and scaled kernels is then evaluated at the desired points. Lanczos resampling is typically used to increase the sampling rate of a digital signal, or to shift it by a fraction of the sampling interval. It is often used also for multivariate interpolation, for example to resize or rotate a digital image. It has been considered the "best compromise" among several simple filters for this purpose. The filter is named after its inventor, Cornelius Lanczos (Hungarian pronunciation: [ˈlaːnt͡soʃ]). (Wikipedia).

What is an enlargement dilation
👉 Learn about dilations. Dilation is the transformation of a shape by a scale factor to produce an image that is similar to the original shape but is different in size from the original shape. A dilation that creates a larger image is called an enlargement or a stretch while a dilation tha

A new facility for HL-LHC is born at Point 1
The final civil engineering works at Point 1 of the High-Luminosity LHC have been completed. The new facility, along with its sibling at Point 5, will house the cutting-edge equipment needed to sustain the ten-fold increase in integrated luminosity promised by the HL-LHC project. #HiLumiLH
