Internship | Object-level feature-based fine-grained change detection

In many computer vision tasks, it is essential to compare two shots of the same object taken at different times and from varying perspectives, while the object itself may also have moved. The challenge is to establish whether there are any meaningful changes to the object, e.g. a scratch, piece of tape, bump, etc. This task requires two capabilities: (1) identifying that the same object is visible in both images despite potential movement, and (2) detecting any actual changes to the object itself. Recent advances in computer vision such as OmniGlue (CVPR 2024), leverage powerful foundation models that have better patch-based representations, facilitating object matching under severe viewpoint variations. To discover changes to the object, almost all methods focus on changes of pixels or pixel regions (e.g. photogrammetry/warping). However, pixel changes are not necessarily interesting; they can also be about shadows, different lighting, reflections from nearby objects. The patch representations from OmniGlue and DINO v2 (2024) are less influenced by such accidental circumstances, and encode the more meaningful features. Can we leverage such representations for feature-based change detection between two views of the same object?

Explore patch representations such as OmniGlue and DINO v2 for the task of establishing correspondences and changes between objects in two views. Investigate how to assess which objects are seen in both views. Research how to find the fine-grained differences between them, such as a scratch, piece of tape, bump, etc.

After the first CV selection, the application process will be conducted by the concerning department. TNO will provide a suitable internship agreement. If you have any questions about this vacancy, you can contact the contact person mentioned below.

For this internship vacancy it is required that the AIVD issues a security clearance (VGB) after conducting a security screening. Take into account that this process may take about 8 weeks. If you have been abroad for more than 6 consecutive months, or if you do not have the Dutch nationality, it may take longer. Read more about security screening on the AIVD website.

Important to be aware of before applying:

• Before the start of the internship, the internship agreement from TNO needs to be signed. For students at a college or university based in the Netherlands, TNO uses the UNL-template (supplemented with a number of specific agreements from TNO). For students of foreign and MBO educational institutions, the TNO internship agreement applies. TNO does not sign any other internship agreements.
• Before the start of the internship, the educational institution will need to confirm in writing that:
• 1) you are enrolled at the educational institution during the internship, and;
• 2) the internship takes place as part of the programme of the study.
• The confirmation of educational institution takes place by signing the UNL template or forms prepared by TNO.
• Interns at TNO must be in possession of a Dutch residential address at the start of the internship. Performance of internship activities from abroad is not possible.
