  • Patent number: 9805486
    Abstract: A user terminal apparatus includes an input receiver, an intersecting-image information obtaining unit and a divider. The input receiver receives input information relating to image-drawing and image-erasing. The intersecting-image information obtaining unit obtains image-drawing input information intersecting image-erasing input information as intersecting-image information when the input receiver receives image-erasing input information. The divider divides the intersecting-image information to erase a portion of the intersecting-image information contained in an erasing area computed from the image-erasing input information when the input information is image-erasing input information.

    Abstract: A processing apparatus estimates a noise amplitude spectrum of noise included in a sound signal. The processing apparatus includes an amplitude spectrum calculation part configured to calculate an amplitude spectrum of the sound signal for each one of frames obtained from dividing the sound signal into units of time; and a noise amplitude spectrum estimation part configured to estimate the noise amplitude spectrum of the noise detected from the frame. The noise amplitude spectrum estimation part includes a first estimation part configured to estimate the noise amplitude spectrum based on a difference between the amplitude spectrum calculated by the amplitude spectrum calculation part and the amplitude spectrum of the frame occurring before the noise is detected, and a second estimation part configured to estimate the noise amplitude spectrum based on an attenuation function obtained from noise amplitude spectra of the frames occurring after the noise is detected.

    Abstract: A pattern recognition system includes a learning unit, a learning unit, a threshold calculation unit, and a determining unit. The learning unit learns, based on learned data of a first pattern, a model for determining whether recognition object data is the first pattern. The learning unit calculates likelihood indicating how likely the recognition object data is the first pattern by using the model learned by the learning unit. The threshold calculation unit calculates a threshold to be compared with the likelihood to determine whether the recognition object data is the first pattern, based on first likelihood that is calculated with respect to learned data of the first pattern and second likelihood that is calculated with respect to learned data of a second pattern. The determining unit determines whether the recognition object data is the first pattern by using the threshold.
