    摘要： A method of processing an ultrasound image includes generating a plurality of two-dimensional (2D) ultrasound images from three-dimensional (3D) ultrasound volume data of an object to be diagnosed, generating a plurality of tissue edge images of an edge of at least one tissue component in the object to be diagnosed based on values of a plurality of pixels forming each of the 2D ultrasound images generated from the 3D ultrasound volume data, and generating a 2D ultrasound image from which a noise component has been removed by discriminating the edge of the at least one tissue component from a position of the noise component based on a difference between a similarity of the edge of the at least one tissue component in the tissue edge images and a similarity of the noise component in the tissue edge images.

    摘要： Provided are a method and apparatus for controlling a sound field through an array speaker. The method includes calculating a coefficient of a filter that controls sound pressure of an input signal, based on a sound pressure ratio of a suppression area that suppresses sound emitted from an array speaker and an emphasis area that emphasizes the sound, and sound pressure efficiency in the emphasis area, generating a plurality of output signals that focuses the sound to the emphasis area by filtering the input signal based on the calculated coefficient of the filter, and outputting a sound field controlled sound based on the generated plurality of output signals. Accordingly, a listener in a predetermined direction and distance from the array speaker can clearly hear sound, without wearing an earphone or a headset so as to focus the sound only to the listener.
