On the choice of band-pass quadrature filters
WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Band-pass quadrature filters are extensively used in computer vision to estimate information from images such as: phase, energy, frequency and orientation, possibly at different scales and utilise this in further processing-tasks. Arguably, local 1 phase is the most desirable … WebThis corresponds to a minimal choice of β= 1 octave. 3. 5 Orientation coverage ... • A set of 8 quadrature pairs of spatial filters are proposed: h k(x,y) = g(x,y,0, ...

WebCommon applications. A common application in electronic music production is in the design of an effects unit known as a "phaser", where a number of all-pass filters are connected in sequence and the output mixed with the raw signal.. It does this by varying its phase shift as a function of frequency. Generally, the filter is described by the frequency at which the … WebThe quadrature filter. Beginning with a causal response, we switched cosines and sines in the frequency domain. Here we do so again, except that we interchange the time and frequency domains, getting a more physical interpretation. A filter that converts sines into cosines is called a `` phase-shift filter" or a `` quadrature filter ."
Web1 de out. de 2014 · The α scale spaces is a recent theory that open new possibilities of phase-based image processing. It is a parameterised class (α ∈] 0, 1]) of linear scale space representations, which allows a continuous connection beyond the well-known Gaussian scale space (α = 1).In this paper, we make use of this unified representation to derive … WebThis article presents a versatile voltage-mode (VM) biquad filter with independently electronic tunability. The proposed structure using one dual-output operational transconductance amplifier, three single-output operational transconductance amplifiers (OTAs) and two grounded capacitors was explored to derive a new VM quadrature …
