🎮 Simulator: 1D Spatial Unsharp Filtering
g = f + k·(f − f_smooth)
k = 1.5
window = 9
σ = 0.04
① f(x) — Original Signal
↓ low-pass filter (moving average)
② f_smooth(x) — Peak Attenuated by Filter
↓ subtraction: f − f_smooth
③ Residual (f − f_smooth) — High Frequencies / Edges
↓ addition: f + k · residual
④ g(x) — Signal with Enhanced Peak
