Anomaly Details
Take a closer look at a single photo or video, with detected edges outlined and video playback controls.
The Anomaly Details screen shows one item you chose from Anomaly Detection. For a photo it applies edge detection once and displays the outlined result. For a video it reads the footage frame by frame, draws outlines on each frame as it plays, and gives you a play and pause control so you can work through the clip at your own pace.

Overview
| Element | Purpose |
|---|---|
| Photo view | A still image with detected outlines drawn on top |
| Video view | Processed video frames with outlines, played back in place |
| Play / Pause | Controls video playback and replays the clip once it ends |
| Back arrow | Returns to Anomaly Detection |
The screen decides for itself which view to show, based on what you picked:
| You picked | What you get |
|---|---|
| A photo (from camera or library) | Photo view only — the video view and Play / Pause are hidden |
| A video (from library) | Video view with Play / Pause visible |
How the outlines are produced
The same analysis is used here as on the live camera screen:
| Step | What it does |
|---|---|
| 1. Convert to grey | Colour is removed so only light and shade matter |
| 2. Soften | A small blur removes speckle that would look like edges |
| 3. Find edges | Sharp changes in brightness are traced |
| 4. Trace outlines | The outer boundary of each shape is followed |
| 5. Draw | Outlines are drawn in bright green, two pixels thick |
Getting Here
- Open Anomaly Detection.
- Tap the three-dot button and choose Pick From Camera or Pick From Photo Library.
- Choose a photo or video. This screen opens automatically with your selection.
There is no way to open this screen on its own — it always follows a pick from Anomaly Detection, which is also why the back arrow always returns you there.
Review a Photo
- The picked photo appears with detected outlines drawn on top. Analysis runs once, as the screen opens.
- The outlined image is added to your detected-images collection, so it is there when you open Review on the previous screen.
- Pinch and study the result as you would any image.
- Tap the back arrow to return and pick something else.
Still photos have no playback controls — the Play / Pause button is hidden for photos. The analysis is not repeated while you look at the result.
Review a Video
- The video starts processing and playing as soon as the screen opens, with outlines drawn on each frame as it goes. Rotation recorded by the camera is corrected automatically, so portrait clips are shown the right way up.
- Tap Play / Pause to pause at a frame you want to study, and again to resume.
- When the clip reaches its end it resets to the start and the button returns to its paused state.
- Tap Play / Pause after the end to replay the clip from the beginning; the frames are processed again as it plays.
- Tap the back arrow to return.
| Behaviour | Detail |
|---|---|
| Playback starts | Automatically, as the screen opens |
| Position checked | Twice a second, to spot the end of the clip |
| At the end | Resets to the start and pauses |
| Added to the detected collection | The first processed frame of the clip |
| Rotation | Taken from the video's own recorded orientation |
Let the clip run through once so every frame has been processed, then replay it and use Play / Pause to stop on the moments that interest you.
Long or high-resolution videos take real time and memory to process, because every frame is analysed as it plays. If playback stutters or the device gets warm, trim the clip shorter before analysing it.
How This Connects
- Where the item comes from. Whatever you picked on Anomaly Detection — a photo taken on the spot, or a photo or video from your device library. Nothing is fetched from the server, so this screen works entirely offline.
- Where results go. Outlined results are added to the same detected-images collection that the live scan fills, reachable through Review on Anomaly Detection. For a photo the outlined image is added; for a video the first processed frame is added, so a long clip does not flood the list. Results stay on the device and are not uploaded to your organisation.
- Permissions are shared. Getting here needs either the camera grant or the photo-library grant, the same ones used by Scan to PDF and QR Code Scanner on the Tools screen and by Photo Drawing. See Permission Required.
- Keeping a finding. To keep and share something you spot, capture it separately and annotate it in Photo Drawing, which saves to your device library and can then be attached to an incident — see Incident Additional Tab — or sent in Chat.
- Offline and reconnect. All processing happens on the device, so signal makes no difference to anything on this screen.
Troubleshooting
| If this happens | What to do |
|---|---|
| The image appears with no outlines | The scene is too flat or too dark for edges to be found; try a different photo or one with more contrast |
| The video view is blank | The clip could not be read. Go back and pick a different video, ideally one recorded on this device |
| Play / Pause is missing | You picked a photo — stills have no playback controls |
| Playback stutters | Every frame is being analysed as it plays. Use a shorter or lower-resolution clip |
| The video plays sideways | Rotation comes from the clip's own recorded orientation; re-record or rotate the clip in your photo app and pick it again |
| Tapping Play / Pause at the end does nothing visible | The clip has reset to the start — tap once more to replay it from the beginning |
| The device gets warm on a long clip | Expected while processing; pause playback or leave the screen to let it settle |
| The result is not in Review | For photos the outlined image is added, for videos only the first processed frame is; scroll the review list to the end |
| You cannot get back to the camera | Use the back arrow — it always returns to Anomaly Detection |
