9 | The default values in the RCT node may not work for your sample, trials should be made |
||
10 | to optimize the parameters. The good parameters should find hundreds, but not thousands of |
||
11 | features in your untilted image for good results. |

14 | 3 | Amber Herold | 1. Presets Manager> send the preset used in "Centered Square" to scope at the center |
15 | 1 | Amber Herold | of a square. |
16 | |||
17 | |||
18 | 3 | Amber Herold | 2. RCT/toolbar> Click on the "acquire" button at the far right to acquire a test image |
19 | 1 | Amber Herold | of which the feature finding algorithm will be applied after the acquisition. |
20 | |||
21 | |||
22 | 3 | Amber Herold | 3. RCT> Check the result of the numbers of feature found. A few hundred but not |
23 | 1 | Amber Herold | thousands would be a good settings. |
24 | |||
25 | |||
26 | 3 | Amber Herold | 4. RCT/Settings> Adjust Min Feature Size (most sensitive) and/or Max Feature Size or |
27 | 1 | Amber Herold | the filters and then repeat 2 and 3 to get better results. |
28 | |||
29 | |||
30 | 3 | Amber Herold | 5. Target templates are applied to the valid raster points to create the final |
31 | 1 | Amber Herold | acquisition and focus targets. The template can be constant, meaning that it is defined |
32 | relative to the image coordinate. The template can also be convolved with the raster |
||
33 | points which will create multiple targets, each defined relative to the coordinate of |
||
34 | the valid raster points. |
||
35 | |||
36 | |||
37 | |||
38 | |||
39 | * Min/Max Feature Size: if < 1, it means faction of the image area. If > 1, |
||
40 | number of pixels. |
||
41 | |||
42 | |||
43 | * List of Tilts to Collect are in the order of data collection |
||
44 | |||
45 | |||
46 | * RCT node has its own drift monitoring after each tilt at the transformed focus |
||
47 | target position. Therefore, drift threshold and drift preset need to be defined. |
