Figure 2From: Discrete shearlet transform on GPU with applications in anomaly detection and denoisingFrequency support of a representative shearlet function ψ j,ℓ,k , inside the pyramidal region P 1 . The orientation of the support region is controlled by ℓ = (ℓ1,ℓ2); its shape is becoming more elongated as j increases (j = 4 in this plot).Back to article page
