Camera preview

After adding a camera or video file in the web interface, a preview of the camera feed or video file should be displayed with detections of faces, bodies and skeleton joints, along with information about individuals in the camera's field of view, such as gender, age, emotions, etc. Detected faces and bodies are highlighted in the preview with bounding boxes (bbox), while skeleton joints are represented with solid or dashed lines.

Variations of bounding boxes (bbox) for detected faces

Bbox indications	Description	Preview
Red corners	A face is detected, a person is not looking at the camera.
Double red corners	A face is detected, a person is looking at the camera.
Red corners in the shape of "+"	Poor image quality or an unsuitable head angle for accurate detection.
Double red corners in the shape of "+"	Poor image quality or an unsuitable head angle for accurate detection, but a person is looking at the camera.
Green corners	A face is identified, a person is not looking at the camera.
Double green corners	A face is identified, a person is looking at the camera.
Green corners in the shape of "+"	A face is identified, but with poor image quality or an unsuitable head angle for accurate detection.
Dashed red-blue corners	A face is detected, a person is within the ROI and not looking at the camera.
Double dashed red-blue corners	A face is detected, a person is within the ROI and looking at the camera.
Red-blue corners in the shape of "+"	Poor image quality or an unsuitable head angle for accurate detection, but the person is within the ROI.
Double red-blue corners in the shape of "+"	Poor image quality or an unsuitable head angle for accurate detection. A person is within the ROI, looking at the camera.
Dashed yellow-green corners	A face is identified, a person is within the ROI, not looking at the camera.
Double dashed yellow-green corners	A face is identified, a person is within the ROI, looking at the camera.
Yellow-green corners in the shape of "+"	A face is identified, a person is within the ROI, but the image quality is poor or a head angle is unsuitable for accurate detection.

Variations of bounding boxes (bbox) for detected bodies

Bbox indications	Description	Preview
Green bbox	The neural detector detects a body, assigns it a unique identifier, and compares it with previously tracked bodies to determine if the person has appeared before. If the person has been in the frame before, the track is continued. If not, a new track is created for the new body with a unique identifier.
Blue bbox with highlighting in the ROI (Region of Interest)	The neural detector detects a body and tracks its position within the ROI. However, the event of entering the ROI is only triggered after the time specified in the run.params.json parameters has passed.

Variations of detected skeleton joints

Indications	Description	Preview
Solid purple line	Skeleton joints with a detection confidence above the threshold (0.5).
Dashed purple line	Skeleton joints with a detection confidence below the threshold (0.5).
