Statuses are made to keep track of your image data's quality. There are four progress statuses, uploading, new, annotate, and review, and three potential end states, complete, discarded, and in some cases error. These statuses can be used as filters in dataset management to make sure you're only exporting images you need, or to browse images pending review, like this one.
On the top, we notice a timeline that indicates the current status of the image. On the top right, the progress button shows us the next stage that it will go to. Pressing this button will progress this image from In Review to Complete, and take us to the next one. When we send an image to the next stage, a timer starts.
This gives us a time span of 30 seconds before this image's status is officially changed, in case we want to change our decision. Once elapsed, this image becomes officially complete. It is immutable, and only an admin can change its status. Within the annotate and review status, an image may also be assigned to a person.
If I select these images pending review and assign them to a user on my team, their avatar will appear within the yellow circle of the review status. New images are considered such because they've never been assigned to anyone and contain no annotations. Finally, archived images have been discarded either during review or by an admin.
Depending on your workflow, your images may go through many statuses. From new to annotated, to in review, and back to annotated, and finally to complete.
