identifying, within the camera-generated visual data, a reflection of at least a portion of data displayed at the display of the computing device by:
computing a similarity score between a part of the remotely-generated visual data and a part of the camera-generated visual data; and
determining that the part of the camera-generated visual data comprises the reflection if the similarity score exceeds a threshold;
modifying the camera-generated visual data to remove the reflection; and
transmitting the modified camera-generated visual data to the at least one remote device for display thereat during the video conference.
