Abstract: A method for extracting a person region includes detecting a face from a raw image input in real time; configuring a search range based on the detected face; extracting an outline of a person region by performing preprocessing on an image within the search range; configuring watershed markers on a background and a foreground of the image within the search range based on the extracted outline; performing a watershed transform based on the configured watershed markers; and separating the person region from the raw image using a result of the watershed transform.

Abstract: A phase shifter according to at least one embodiment of the present disclosure has a housing provided on both surfaces with respective shifting units. Each shifting unit is composed of a fixed board and a moving board. Movement of the moving board causes a phase-shifted signal to be simultaneously transferred from both surfaces of the housing to output ports. This allows more effective use of the space of the phase shifter and therearound.

Abstract: A clustering method includes configuring a network with clustering target objects; collecting significance of the clustering target objects; performing network embedding for outputting a set of vectors representing neighboring objects of the clustering target objects constituting the network using a neural network; and performing clustering on the clustering target objects using the set of vectors and information on each of the clustering target objects, wherein the neural network is trained so that neighboring objects having high significance are output with higher probability.
