Note that you may get slightly different results because some processes are random and do not always give exactly the same result.
High correspondence (strict)
Set Panaustik in the duplicate mode with a “hight” level of correspondence (slider fully right). In this configuration, only images with a high degree of similarity (content and framing) are detected.
We obtain 4/5 groups of two/three images. Images with excessive variations in sharpness, lighting or color are not detected. Note that the upside down image of the ceil is correctly detected!
Set the duplicate mode with a “low” level of correspondence (slider fully left) and then rescan.
This time, we get 8/9 groups. Images with large variations in lighting or sharpness are detected. On the other hand, some panoramas begin to appear. They correspond to images which are superimposed on at least half of their surface! Similarly, the ceil group detects images with a low rotation as duplicate.
Set Panaustik in the panorama mode with a “hight” level of similarity (slider fully to the right). In this mode, unlike the duplicate mode, there are no constraints on the size nor on the relative position of the images
The analysis shows 28 images in 9 groups.
When images contain GPS data, the “tooltip” shows the picture location (Internet connection required).
Note in particular, the ceil group where images with large rotation are detected.
Checking or not the check for quick search of panoramas does not change significantly the result. There is, against a real difference in speed!
Configure Panaustik in panorama mode with a “low” level of similarity (slider to the left). In this mode, the images are analyzed more deeply to bring out maximum similarity (sometimes too much).
This time, uncheck the box for quick search of panoramas.
This mode can detect images taken with different focal lengths as for the images of Venice.
If the settings of the quick setup are not adapted in a particular situation, the easiest way is to peforms a quick setup, and then go to advanced options to adjust the desired parameters.
