# High Pass Filter

You can choose from the following processing options:

- Gauss: In Gauss mode, you can specify a smoothing factor along the Smoothness X and Smoothness Y. The Settings tab also displays the Sigma X and Sigma Y values for the standard deviation of grey values of the Gaussian curve along the (x, y) axis.
- Mean: This mode will smooth the input image via a mean filter of user-selectable kernel size. You can specify the Kernel Height and Kernel Width of the kernel.
- Median: This mode will smooth the input image via a median filter of user-selectable kernel size. You can specify the Kernel Height and Kernel Width of the kernel.

Cognex recommends you experiment with the different filters to get the desired results. High Pass Filter
