Figure 1From: Discrete shearlet transform on GPU with applications in anomaly detection and denoisingFrequency plane and frequency support. (a) The tiling of the frequency plane R ̂ 2 induced by the shearlets. (b) Frequency support Σj,ℓof a shearlet ψ j , ℓ , k ( 1 ) , for ξ1 > 0. The other half of the support, for ξ1 < 0, is symmetrical.Back to article page
