Summary
The Filter Manager in uScope Navigator lets you create filter sequences that can be applied to:
- Overview Images (images captured by the overview camera)
- Objective Images (images captured by the objective camera)
- Whole Scan Images (images created by stitching scan fields together)
Details
Filters included in a filter sequence are applied to the source image in order. For example, if the filter sequence is composed of the following filters:
- Flat-Field Correction
- Brightness
- Contrast
Flat-field correction is applied to the image first, followed by brightness adjustment, and finally contrast adjustment.
Benefits of programmed filter sequences is that they can be named & saved and they are repeatable.
Note
Long sequences of filters can take a long time to process. Convolutions, such as Gaussian Blur and Gaussian Sharpen, take an exceptionally long time depending on how they are configured.
Filters
The following filters are supported for the various filter sequence types:
| Filter | Overview Camera | Objective Camera | Whole Scan Image |

| Bilateral Smoothing | — | — | yes |
| Blur | yes | yes | yes |
