“…of the scale-normalized spatio-temporal quasi quadrature entity (73) f (x, y, t) = g(x, y; s 0 ) g(t; τ 0 ) = 1 (2π) 3/2 s 0 √ τ 0 e −(x 2 +y 2 )/2s0 e −t 2 /2τ0 , for which the spatio-temporal scale-space representation is of the form (113) L(x, y, t; s 0 , τ 0 ) = g(x, y; s 0 + s) g(t; τ 0 + τ ), the spatial and temporal scale estimates will according to the theoretical analysis in (Lindeberg [44,45]) be given by ŝ = γ s s 0 2 − γ s s 0 , If we want to calibrate the spatial and temporal scale estimates such that the spatial and temporal scale estimates are equal to ŝ = s 0 and τ = τ 0 for a Gaussian blink of spatial extent s 0 and temporal duration τ 0 , we should therefore calibrate the phase compensated scale estimates ŝQ (x,y,t)L,comp and τQ (x,y,t)L,comp according to ŝQ the spatial scale estimate for a diffuse Gaussian edge will by combination of (106) with (120) be given by (123) ŝ = 2 + Γ s Γ s s 0 , whereas the temporal scale estimate for a Gaussian onset ramp will by combination of (107) with (121) be given by (124) τ = 1 + Γ τ Γ τ τ 0 .…”
