Abstract: A server includes a session management device establishing a video call session between a first electronic apparatus of a first user and a second electronic apparatus of a second user, a communication device receiving match satisfaction calculated from the first electronic apparatus through the video call session, an image analysis device obtaining first feature point distribution information from a face image of the first user and obtaining second feature point distribution information from a face image of the second user, a processor training a machine learning model by using the first feature point distribution information, the second feature point distribution information, and the match satisfaction and estimating the match satisfaction of the first user for each of standby users by using the trained machine learning model when a video call connection between the first electronic apparatus and the second electronic apparatus is terminated, and a user management device selecting a third user, who becomes a

Abstract: An electronic apparatus making a video call includes a processor dividing an image of a user of the electronic apparatus into a plurality of areas and editing an area, which is not selected from the user, from among the plurality of areas to generate the edited image, an input device receiving a selection input to select at least one area among the plurality of areas from the user, and a communication device transmitting the edited image to an electronic apparatus of a video call counterpart.

Abstract: The communication method includes performing, by a first terminal, consecutive video call with at least one or more second terminal; selecting, by the first terminal, at least one or more representative frame from among a plurality of frames of an image being photographed during each video call; detecting, by the first terminal, a face from the at least one or more representative frame; generating, by the first terminal, a face recognition result that includes information on a number of the faces detected from the at least one or more representative frame; outputting, by the first terminal, the face recognition result to a server; and upon completion of the video call with the at least one or more second terminal, performing, by the first terminal, video call with a third terminal selected based on the face recognition result from the server.

Abstract: A method for censoring inappropriate images during a video call is disclosed. The method includes: receiving, from a first terminal, a stream including a plurality of images captured by the first terminal; attempting to detect a face in each of one or more sample images selected among the plurality of images included in the stream; determining that the face has not been detected in at least some of the sample images; performing image processing on at least one of the plurality of images included in the stream; and displaying the plurality of images included in the stream.
