Edge detection scheme comparison on the vesicle image. Comparison of different edge detection schemes applied to the vesicle image. a) raw output from out curvelet-based scheme; b) Canny edge detector with thresholds 0.12 and 0.35; c) odd Gabor filter with σ = 2 and ω = 0.5.; d) odd Gabor filter with σ = 6 and ω = 0.33.
