Nonlinear Filter

A nonlinear (or non-linear) filter is a filter whose output is not a linear function of its input. In short, the input values produce output values that are not linear translations. It may be as simple as an exponential increase, as in a squared, or cubed output. Nonlinear filters are useful in image processing and convolutional neural nets.
