A stencil is a Filter where every pixel’s next value a fold of its neighbors.
- Examples
- Box Blur, Gaussian Blur
- Each pixel is a weighted average of its neighbors
- Conway’s Game of Life
- Each pixel is on or off based on different orientations of its neighbors
- Jacobi Method, Gauss-Seidel Method
- Each pixel is a weighted average of its neighbors, where Jacobi is a FIR Filter and Gauss-Seidel is an IIR Filter
- Box Blur, Gaussian Blur
