Abstract: An electronic device according to an embodiment includes a communication circuit and a processor. The processor is configured to: obtain a plurality of images; obtain feature information associated with the plurality of images, the feature information indicating a first probability that a body part is present in the plurality of images; obtain, using encoding layers, code information associated with the body part having dimensions smaller than dimensions associated with the feature information; obtain, using decoding layers, heatmap information indicating a second probability that one or more vertices corresponding to the body part exist, the second probability also indicating that the body part has dimensions greater than dimensions associated with the code information; and obtain mesh information that indicates a shape of the body in a virtual three-dimensional space, the mesh information comprising being based on the one or more vertices.

Abstract: An electronic device includes memory storing instructions; and one or more processors, wherein the instructions, when executed by the one or more processors, cause the electronic device to input, into a neural network, at least one image, from among images that are obtained from different viewpoints, to obtain first information indicating locations of body parts of a subject included in the images, wherein the first information includes first location data indicating a first locations of portions of the body parts within a first image from among the images, and wherein the first locations are determined based on a first visibility values of the portions in the first image; obtain, based on the first information, second information indicating a second locations of the body parts at moments when the images were obtained; and track positions of the body parts in a virtual three-dimensional space based on the second information.

Abstract: The electronic device according to various embodiments include a memory configured to store instructions and at least one processor configured, when executing the instructions, to obtain a first video sequence including a visual object corresponding to a body; obtain a local posture sequence of the visual object that indicates postures of at least one visual element of the visual object in the first video sequence, the at least one visual element of the visual object corresponding to at least one joint of the body; obtain a global motion sequence of the visual object, based on a difference between the postures of the at least one visual element, the postures of the at least one visual object obtained by using the local posture sequence; and obtain a second video sequence, based on the local posture sequence and the global motion sequence.
