Abstract: Methods, systems and processor-readable media for classifying human coactivity performed jointly by two humans shown in an image or a sequence of frames of a video. A 2D convolutional neural network is used to identify key points on the human body, such as human body joints, visible within the image or within each frame, for each of the two people performing the coactivity. An encoded representation of the key points is created for each image or frame, the encoded representation being based on distances between the key points of the first person and key points of the second person. The encoded representation for the image, or a concatenated volume of the encoded representations of the frames, is processed by a fully-connected neural network trained to classify the coactivity.

Abstract: Methods and apparatus for operating an optical switch in response to in-band operation and management (OAM) signals. The switch monitors for presence or absence of light at its input ports. In response to new light being present after a period of absence, the switch directs the new light to an internal receiver, which obtains control information from the light. This control information indicates an output port which is to be optically coupled to the input port. The switch then reconfigures itself to perform such an optical coupling. If light becomes absent again at the input port, the process can repeat.
