How do I simulate an A/B test?

Open this page and use the live Image Processing Chain tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive an A/B test from your own measurements.

Each output pixel is a weighted sum of its 3×3 neighborhood. Slide this kernel over an image and you get blur, sharpening, or edge maps — the exact operation a convolutional neural network learns.

Governing equation

(f * g) (t) = \int_{- \infty}^{\infty} f (τ) g (t - τ) d τ (σ = 0.4, taps = 3)

Reading this result: Convolution slides the 3-tap kernel over the image; each output pixel is a weighted sum of its 3×3 neighbors. At sigma ≈ 0.4 the weights stay tightly concentrated, so edges and fine detail survive and high-frequency structure is preserved.

Build a signal from a few sine tones plus noise, and the discrete Fourier transform recovers exactly which frequencies are present — the foundation of all signal processing.

Governing equation

X_{k} = n = 0 \sum N - 1 x_{n} e^{- 2 π ik n / N} (N = 256, O (N lo g N))

Reading this result: The FFT splits this 2-tone signal into bins: each input sinusoid at 4, 9 appears as a distinct spike, and with noise at 0 the baseline between them stays clean.

About this simulation

The full Image Processing Chain tool models an A/B test with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
