Filters provide an easy to use, yet powerful tool to remove interfering elements (like noise or ice gradients) from an image. Here, a set of different filters are provided which all apply a filter onto the input stack of images.
A stack of images/3Ds or an individual 3D will be subjected to the selected filter with its respective filter parameters. For more detail on the capabilities of the available filters and their parameters, consult the respective process section below. Since most of the filters just have one input (stack of images) and one output (stack of images w/ applied filter), only divergent in-/outputs are mentioned.
Applies a Butterworth Filter with the chosen parameters to the images. A butterworth filter has a smooth transfer function without any discontinuity. The filter functions used in this logic are:
B(Low Pass)= 1/ (1+[D(u,v)/DL ]2n)
B(High Pass)= 1- (1/ (1+[D(u,v)/DH]2n))
where D(u,v) is the distance from the origin, n is the order of the filter and DL/DH is the cut frequency.
| Parameters | Description |
| Type | Select whether you want to apply a highpass or lowpass filter |
| pass-band | Order of the filter n |
| showFilterFunction | Use this option to change the output consisting of complex images showing the filter function instead of the filtered images |
| stop-band | Upper or lower frequency cut-off DL / DH, depending on whether high- or lowpassfilter is selected |

In this paragraph, the “HOW a logic works under the hood” and WHY someone should use it can be elaborated with higher detail. Describes a scenario in an image processing workflow where this logic can be used to solve the resulting problem. Also, wikipages, publications or anything else describing the theory behind an algorithm should be linked here, if applicable.
