Abstract: In one embodiment, a method includes receiving a request to establish an audiovisual streaming session between a first device and a second device; determining a level of network connectivity for a network associated with the first device or the second device; receiving data from the first device. The data may the data represent facial expressions of a user in a video captured by the first device. The data may be generated by the first device using the video based on: detections of a face and facial features of the user in the video and application of one or more subtractive filters using the detected face and facial features. The subtractive filters may be selected based on the level of network connectivity. The method may also include sending the data to the second device with instructions to process the data and display a representation of the user's facial expressions.
