    • A method and apparatus for processing an ultrasound image are provided. The method includes determining similarities between a first two-dimensional (2D) ultrasound image, among 2D ultrasound images of a three-dimensional (3D) ultrasound image, and the 2D ultrasound images. The method further includes generating a predetermined number of similar ultrasound images with respect to the first 2D ultrasound image based on the similarities. The method further includes generating 3D volume data based on the predetermined number of the similar ultrasound images. The method further includes removing noise from the 3D volume data. The method further includes generating another 3D ultrasound image based on the noise-removed 3D volume data.

    • A method and apparatus for localizing a sound image of an input signal to a spatial position are provided. The method of localizing a sound image to a spatial position includes: extracting from a head related impulse response (HRIR) measured with respect to changes in the position of a sound source, first information indicating a reflection sound wave reflected by the body of a listener; extracting from the HRIR second information indicating the difference between sound pressures generated in two ears, respectively, when a direct sound wave generated from the position of the sound source arrives at the two ears, respectively, of the listener; extracting third information indicating the difference between times taken by the direct sound wave to arrive at the two ears, respectively, from the HRIR; and localizing a sound image of an input signal to a spatial position by using the extracted information. According to the method and apparatus of the present invention, by using only important information having influence on sound image localization of a virtual sound source extracted from the HRIR, the sound image of the input signal can be localized to a spatial position with a small number of filter coefficients.
