Apply intensity filters to an image in the workspace.
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
