Description

Apply intensity filters to an image in the workspace.
Note: 3D median filter is currently incompatible with 5D hyperstacks

Parameters

Input image (default = "") Image to apply filter to.

Apply to input image (default = "true") Select if the filter should be applied directly to the input image, or if it should be applied to a duplicate, then stored as a different image in the workspace.

Output image (default = "") Name of the output image created during the filtering process. This image will be added to the workspace.

Filter mode (default = "Difference of Gaussian 2D") Filter to be applied to the image.

- Difference of Gaussian 2D Difference of Gaussian filter (2D) Used to enhance spot-like features of sizes similar to the setting for "Filter radius".

- Gaussian 2D.

- Gaussian 3D.

- Gradient 2D.

- Maximum 2D.

- Maximum 3D.

- Mean 2D.

- Mean 3D.

- Median 2D.

- Median 3D.

- Minimum 2D.

- Minimum 3D.

- Ridge enhancement 2D enhances ridge-like structures in the image.

- Rolling frame filters the image at each frame based on frames before and/after. The frame window over which the statistics are calculated is user-controllable..

- Variance 2D.

- Variance 3D.

Filter radius (default = "2.0") Range the filter is calculated over. Often also referred to as "sigma". Value specified in pixel units, unless "calibrated units" is enabled.

Calibrated units (default = "false") Choose if filter radius is specified in pixel (set to "false") or calibrated (set to "true") units. What units are used are controlled from "Input control".

Rolling filter method (default = "Average") Statistic to apply for rolling frame filtering.
Window half width (frames) (default = "1") Number of frames before/after target frame to be used for rolling frame filtering. For example, averaging over a half window width of 3 will use 3 frames before the target frame, 3 frames after and the target frame itself.

Window mode (default = "Both sides") Controls which frames are used in the rolling frame filter calculation
