Wildbook provides several ways to automatically and manually access the Image Analysis Pipeline to identify individual animals, as well as to perform by-eye individual ID. Wildbook assists you in photo ID but never makes a decision for you. You can find answers to frequently asked questions about matching here.
Automated Detection and ID with Encounter submission¶
When you Report an Encounter of a single animal, if you set the species to one supported by the Image Analysis Pipeline, Wildbook will automatically perform the following steps:
- Send each submitted image to Detection to find one or more Annotations in each photo. In the event that Detection doesn’t find any animal in the photo, users can use Manual Annotation).
- Depending on the type of Annotations returned (its “Image Analysis Class”), such as “whale_orca” or “panthera_uncia”, route each Annotation to one or more ID algorithms.
- If the location ID (or “study site”) was set during the submission, the pipeline will limit candidate matches to only that study site.
- Consolidate all Annotation match results into a single page for your review and ID assignment (e.g., setting an existing individual ID or assigning a new ID). See Reviewing Match Results to understand the results page. The Encounter page also allows you to set individual ID later, and you can return to these match results in the future as well.
Because Detection and Identification reside in a queue of computer vision actions requested by all users of your Wildbook, you may not immediately see the results of the Image Analysis Pipeline.
If you see green bounding boxes on images in your submitted Encounter, then Detection has completed. After submission, you may need to periodically refresh the Encounter page for the bounding boxes to appear.
- whale_orca+fin_dorsal (bounding box around the dorsal fin)
- whale_orca (bounding box around the whale body)
If you see green bounding boxes on images in your submitted Encounter and match results appears in the menu of any image, then Identification has started or completed. After submission, you may need to periodically refresh the Encounter page for the bounding boxes to appear and match results to be ready. Click match results to review potential ID matches.
See Reviewing Match Results for more information.
Automated Detection and ID with Bulk Import¶
After a successful Bulk Import, Detection and Identification can be run from the Import summary, allowing for large scale processing. However, this can also cause delays for other Users attempting to use the Image Analysis Pipeline and its job queue. See Bulk Import for more information.
Manual Annotation with Automated ID¶
While Wildbook uses advance machine learning to find and label animals in images, it always has a probability of missing an Annotation. Wildbook allows you to draw additional bounding boxes on an image, label their viewpoints (e.g., “left”, “right”, etc.), and their classes (e.g., “whale_fluke”, “panthera_uncia”, etc.). Once a manual Annotation has been created, its will appear as a normal Annotation on an image and will allow you to manually start a match. See Manual Annotation for more information.
Removing an Annotation¶
To remove an Annotation from machine learning-based Detection or Manual Annotation, go to Encounter Gallery and select Remove Annotation.
Removing a single annotation:¶
- Removing an Annotation from an image will not remove the image on the Encounter it’s referenced in. (Note: This is only applicable for images referenced on a single Encounter.)
Removing multiple annotations:¶
- Removing all the Annotations that are only present on a single Encounter will automatically remove the record of that image on that Encounter.
- If other Annotations of the same image are referenced in other Encounters, those other Annotations and the image’s record will still be present in those Encounters.
Manually Starting a Match¶
For a matchable Annotation, you can start or re-run matching from the Encounter page Gallery by selecting start match or start another match from the menu for the Annotation.
Choose criteria to match against dialog box appears and allows you to:
- multi-select location IDs to match against, allowing you to remove unlikely locations from the results. If set, the location ID of the Encounter will be selected by default.
- filter to only your data
- select one or more algorithms to use for identification
Click Match to start the matching process.
Reviewing Match Results¶
To review the results of the automated matching process, select match results from the menu on the Annotation in the Encounter Gallery. If you recently submitted the Encounter, you may need to wait and then refresh your browser periodically for Wildbook to process the results from automated Detection before the match results menu option appears.
Each match result page may show one or more sets of matches, potentially displaying:
- one algorithm match for one annotation (e.g., by clicking start another match on an annotation for which only one ID algorithm is configured)
- multiple algorithm matches for one annotation (e.g., by clicking start another match on an annotation for which multiple ID algorithms are configured)
- multiple algorithm matches for multiple annotations (e.g., a new Encounter submission with multiple photos)
The information displayed depends on where in Wildbook the Image Analysis Pipeline was called from and for which species.
Match results page sections¶
The following sections make up the matching results page.
A banner labeled Matching results for at the top of the page provides a link to the related encounter and the associated Marked Individual, if an ID has been assigned to the Encounter.
Click to expand the Instructions section to get instructions for reviewing matches on the page. Some of those are repeated here:
- Hover mouse over results to compare candidates to target.
- Links to the corresponding encounters and individuals are next to each match score.
- Select correct match by hovering over the correct result and checking the checkbox
- Use the buttons to switch between result types:
- Individual Scores: This is the default. It computes one match score for every individual in the database. This is the aggregate of each image score for that individual.
- Image Scores: computes the match score for every annotation in the database when compared to the query annotation
- Adjust the number of results that display in each list by changing the value in Num Results and selecting set.
Results: One ranked set per annotation per algorithm¶
Each block of ranked results represents the top-N matches (default top 12) to an Annotation in descending order. Rank 1 is the top suggested match, and each successive match is presented with relatively less confidence. Roll over each row in the list to review the potentially matched annotations. The annotation from your encounter appears on the left, labeled as the TARGET image. Potential candidates for matching appear on the right side, labeled to match their position in the list.
- Rank: The position in the listing (1,2,3,4, etc.).
- Match score: The match score represents the numeric value returned from the algorithm. These scores are not standardized between algorithms or platforms and are generally not bounded. For more information about interpreting algorithm scores, see Identification.
- Encounter link: Opens a new tab to the potential match encounter.
- Inspect: Opens a new page focused on the features being matched. Areas that are highlighted display potentially matched features. Not every algorithm will provide additional detail. Only the first 12 matches may have additional detail.
- Checkbox: Select the checkbox to indicate that an encounter is a match with the target annotation.
Setting the ID using the checkbox¶
In addition to setting the Individual ID from the Encounter page, you can set the ID directly from the match results using the checkbox on any listed result. By clicking the checkbox, one of the following results will be suggested:
- If the annotation is on an encounter for which the ID has not yet been set and the candidate annotation does not have an ID, selecting the checkbox will display a new option in the upper right that includes:
- a typeahead form field that allows you to enter a new ID to assign to both encounters or to look up an existing ID to assign to both encounters.
- The button Set individual on both encounters that allows you to set the ID from the form field. Both annotations and their respective encounters now belong to the same marked individual.
- If the annotation is on an encounter for which the ID has not yet been set and the candidate annotation has an ID set, selecting the checkbox will display a new button in the upper right Set to individual. Click the button to assign the suggested individual ID to the annotation and its Encounter. Both annotations and their respective encounters now belong to the same marked individual.
- If the annotation is on an encounter for which the ID has been set and the candidate annotation has a different ID set, selecting the checkbox will display a new button in the upper right Merge individuals. Click Merge individuals to merge the two Marked Individuals into a single record, assigning all encounters from both previously individuals to a single individual.
Visual Matcher is a separate, very limited user interface to support visual matching of encounters without computer vision. To access the Visual Matcher, select visual matcher on the annotation menu. Visual Matcher was largely developed to support giant manta matching before the availability of computer vision. It has very limited value outside of that task and the MantaMatcher.org platform.
