Abstract: Provided is a method of operating a device for extracting a style-based sketch and a method of training a neural network. Through a neural network for extracting a style-based sketch, a sketch obtained by imitating a style may be extracted by precisely detecting lines showing sketches from the color image and the reference image.

Abstract: A memory device includes a test mode detector circuit that determines whether the memory device has entered a test mode based on at least one test mode entry signal received through at least one pin of a plurality of pins and generates a test mode detection signal, and a test pad connection circuit that electrically couples a first pin of the plurality of pins to a dedicated test pad of the test mode such that a signal applied to the first pin is transmitted to the dedicated test pad based on the test mode detection signal.

Abstract: The present invention is directed to an apparatus for coating a surface of a 2-D or 3-D extrusion material, which comprises a rail unit installed on a base with an elastic member interposed therebetween to be elastically and vertically movable, thereby serving to isolate a coating surface and a non-coating surface from each other while elastically supporting the delivered 2-D or 3-D extrusion material; a coating unit for applying a certain amount of coating liquid to the specific coating surface of the extrusion material at random; and an air knife for blowing air at a constant pressure to the coating liquid applied onto the extrusion material and diffusing the coating liquid to apply the coating liquid at a uniform thickness on the coating surface of the extrusion material.
