Filter image
Description
Apply intensity filters to an image in the workspace.Note: 3D median filter is currently incompatible with 5D hyperstacks
Parameters
- Input image
- Description: Image to apply filter to.
- Type: InputImageP
- Apply to input image
- Description: 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.
- Type: BooleanP
- Default value: true
- Output image
- Description: Name of the output image created during the filtering process. This image will be added to the workspace.
- Type: OutputImageP
- Filter mode
- Description: 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. - Type: ChoiceP
- Default value: Difference of Gaussian 2D

- Description: Filter to be applied to the image.
- Filter radius
- Description: Range the filter is calculated over. Often also referred to as "sigma". Value specified in pixel units, unless "calibrated units" is enabled.
- Type: DoubleP
- Default value: 2.0
- Calibrated units
- Description: 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".
- Type: BooleanP
- Default value: false
- Rolling filter method
- Description: Statistic to apply for rolling frame filtering.
- Type: ChoiceP
- Default value: Average
- Choices:
- Average
- Median
- Minimum
- Maximum
- Standard deviation
- Sum
- Window half width (frames)
- Description: 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.
- Type: IntegerP
- Default value: 1
- Window mode
- Description: Controls which frames are used in the rolling frame filter calculation
- Type: ChoiceP
- Default value: Both sides
- Choices:
- Both sides
- Previous only
- Future only
