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
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.
