In one aspect, a first device includes at least one processor and storage with instructions executable by the processor to receive input from a camera and to identify, based on the input from the camera, a first lighting condition of a scene showing a user. Responsive to the first lighting condition satisfying a first criterion, the instructions are executable to transmit a first video stream showing the user's face as captured by the camera to a second device. Responsive to the first lighting condition not satisfying the first criterion, the instructions are executable to use a model to generate a 3D representation of the user's face according to one or more parameters related to the user and to transmit a second video stream to the second device that shows the 3D representation. The model is also trained under lighting conditions satisfying one or more criteria.

Use of 3D/AI models to generate 3D representations of video stream users based on scene lighting not satisfying one or more criteria

An electronic device is provided that includes an infrared (IR) camera configured to obtain user image data and user profile image data. The electronic device also includes a processor, and a data storage device having executable instructions accessible by the processor. Responsive to execution of the instructions, the processor generates latent space data based on the user image data and user profile image data, and forms an output image using generative modeling of the latent space data.
