	~~<!-- a~~ one~~-sentence description -->~~		4 Functions for frequency domain customizable filtering in one or two dimensions. [http://www.avisynth.nl/users/vcmohan/FFTQuiver/FFTQuiver.htm Full Description]

			[[FFTQuiver]] plugin has two main functions: F1Quiver, F2Quiver. To visualize the frequency spectra and correctly specify filters, two supporting functions are also included. These are F1QTest and F2QTest. These have identical parameters with the processing functions for ease of scripting.

			*F1Quiver and F1QTest transforms image data row by row into one dimensional spatial frequency domain.
			*F2Quiver and F2QTest as the name implies converts whole of image through a 2d transform into spatial frequency domain.

			These functions have a large number of cascadable frequency domain Gaussian and Butterworth filters for image processing.F1Quiver has a custom filter facility also. Homomorphic filtering can also be done with these functions.

			*For AviSynth+ see [[FQPlus]], includes high bit depth colorspace support and 64-bit.
