Abstract: An apparatus for identifying a warship receives a warship image, estimates a photographing angle and a photographing altitude of the warship from the real warship image, generates virtual warship images from stored virtual warship models based on the estimated photographing angle and photographing altitude, generates virtual warship part images in which main parts are classified and displayed for each of the virtual warship images, generates a part segmentation image in which main parts are classified and displayed for the real warship image, and outputs a type and class identification result of the warship by calculating similarity between each virtual warship part image and the part segmentation image.

Abstract: An apparatus and method for calibration between wide angle-narrow angle lenses through a dual-ChArUco board is disclosed. A method of calibration between wide angle-narrow angle lenses through a dual-ChArUco board includes recognizing a first pattern through a wide-angle lens of a first sensor and recognizing a second pattern through a narrow-angle lens of a second sensor, storing the first pattern and the second pattern; and calibrating the stored first pattern and the stored second pattern.

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.
