    Abstract: A separation signal generation unit generates a plurality of separation signals which are independent from one another from the mixed signals for one frame which are converted into those in a frequency region. A mask processing unit judges a noise condition of a first separation signal for each frequency bin on the basis of the first separation signal and second separation signals. The mask processing unit further removes a first noise component obtained on the basis of a judgment result on the noise condition from the first separation signal. A noise amount measuring unit measures the amount of noise in the first separation signal. A noise signal selection unit selects a noise signal for each frequency bin on the basis of the amount of noise measured by the noise amount measuring unit. A noise removing unit removes a second noise component from a noise removal signal inputted from the mask processing unit. The noise removing unit outputs the noise removal signal obtained by removing the second noise component as a target signal.

The present invention provides an information processing apparatus in which a first slice information group, which is multiple pieces of slice information obtained as a result of extraction from 3D voxel information using a first three-dimensional region mask extracting the 3D voxel information, is stored, wherein the information processing apparatus: receives input regarding a second three-dimensional region mask; acquires second mesh information constituting the second three-dimensional region mask; determines an internal region, which is a region inside the second mesh information, and an external region, which is a region outside the second mesh information, for each slice information in the first slice information group, based on the second mesh information; and outputs the first slice information group such that the internal region and the external region are visually distinguished from each other. With this information processing apparatus, it is possible to easily extract and observe a three-dimensional region of interest from 3D voxel data.

    Abstract: In a noise suppression apparatus, an index setter sets an exponent K that is a positive value. A factor setter variably sets a suppression factor according to the exponent K. A noise suppressor generates an audio signal from which a noise component is suppressed through noise suppression process of suppressing a Kth power of an amplitude of the noise component at each frequency thereof in a Kth power of an amplitude of the audio signal at each frequency thereof to a degree determined according to the suppression factor set by the factor setting part. Preferably, the index setter sets the exponent K to a value less than 0.1.
