A method of sharing physical target boards in electronic conferences, the method comprising: capturing video by a camera of a computing machine participating in an electronic conference, the camera oriented to include a physical target board in its field of view; transforming the captured video to generate output video, the output video providing an enhanced view of the physical target board; and transmitting the output video to a set of other computing machines participating in the electronic conference, to enable a user of each of the set of other computing machines to see the enhanced view of the physical target board from the respective computing machine, wherein the physical target board is oriented at an angle relative to the camera such that the camera does not have a direct, face-on view of the physical target board, and wherein transforming the captured video includes performing a perspective deskew operation to render images of the physical target board in the output video from a face-on perspective, and wherein transforming the captured video further includes: identifying a set of edges of the physical target board; characterized by overlaying a border that follows the set of edges to visually accentuate the physical target board in the output video, and wherein the method further comprises, prior to transforming the captured video, performing a board detection operation on the captured video to identify the physical target board within the field of view of the camera, by identifying a set of quadrangles within the field of view of the camera; and selecting a quadrangle, from the identified set of quadrangles, that has characteristics that most closely match a set of predetermined expected characteristics of physical target boards. capturing video by a camera of a computing machine participating in an electronic conference, the camera oriented to include a physical target board in its field of view; transforming the captured video to generate output video, the output video providing an enhanced view of the physical target board; and transmitting the output video to a set of other computing machines participating in the electronic conference, to enable a user of each of the set of other computing machines to see the enhanced view of the physical target board from the respective computing machine, wherein the physical target board is oriented at an angle relative to the camera such that the camera does not have a direct, face-on view of the physical target board, and wherein transforming the captured video includes performing a perspective deskew operation to render images of the physical target board in the output video from a face-on perspective, and wherein transforming the captured video further includes: identifying a set of edges of the physical target board; characterized by overlaying a border that follows the set of edges to visually accentuate the physical target board in the output video, and wherein the method further comprises, prior to transforming the captured video, performing a board detection operation on the captured video to identify the physical target board within the field of view of the camera, by identifying a set of quadrangles within the field of view of the camera; and selecting a quadrangle, from the identified set of quadrangles, that has characteristics that most closely match a set of predetermined expected characteristics of physical target boards. identifying a set of edges of the physical target board; characterized by overlaying a border that follows the set of edges to visually accentuate the physical target board in the output video, and wherein the method further comprises, prior to transforming the captured video, performing a board detection operation on the captured video to identify the physical target board within the field of view of the camera, by identifying a set of quadrangles within the field of view of the camera; and selecting a quadrangle, from the identified set of quadrangles, that has characteristics that most closely match a set of predetermined expected characteristics of physical target boards.
