Shuttle & Find View
Besides the Shuttle & Find tool in the Left Tool Area, the S&F (Shuttle & Find) view is visible in the Center Screen Area of the ZEN software. If the S&F view is selected, the S&F tab and S&F Correlation tab will appear as specific view options under the image area.
S&F Correlation Tab
Here you find all functions to overlay (correlate) two images.

Parameter |
Description |
|
|---|---|---|
|
Transform |
Here you select which image will be transformed. Choose via the Left Image/Right Image buttons, which image should be transformed in the other. During transformation, a pixel in the overlay image is calculated by using pixels of the two original images that shall be overlaid/merged. |
|
|
Interpolation |
Here you can select one of the following interpolation methods: |
|
|
- |
Nearest Neighbor |
The gray value of the resulting pixel in the overlay image is made of a pixel which is located next. This interpolation method is very fast. |
|
- |
Linear |
The resulting or calculated pixel in the overlay image is assigned to a gray value, which is the result of a linear combination of gray values derive from pixels located nearby (in the original image). |
|
- |
Cubic |
The calculated pixel in the overlay image is assigned to a gray value, which is calculated by means of a polynomial function using gray values of pixels in the original images; these pixels are located nearby the calculated pixel. |
|
Mirror image |
Here you can mirror the image horizontally or vertically. Therefore simply click on the corresponding button. Mirroring an image is necessary, when the loaded image shows a different orientation than the live image. |
|
|
Show Correlation |
Activated: Opens the correlated image in a new image document/new container. |
|
|
Set correlation points |
Enables you to set 6 points (3 points in each image) as correlation markers in a row, see Correlating Two Loaded Images. |
|
|
Reset |
Deletes all correlation points in the images. |
|
|
Create Correlation |
Active only if all correlation points are set in both images. Creates a correlative overlay image. A third image container with the correlated image will be opened in the Center Screen Area and the Show Correlation checkbox will be activated automatically. |
