  • Publication number: 20200286214
    Abstract: Image processing using a machine learning model is enabled, thereby accurately reducing noise to improve image quality. A medical image is acquired; and it is evaluated whether noise in the medical image exceeds a predetermined reference value. A noise reducer reduces the noise of the medical image that has been determined to include noise that exceeds the reference value. The noise of the medical image is reduced using a machine learning model constructed by collecting a plurality of learning data sets that include an image with noise as input data and an image without noise as output data. The machine learning model includes a plurality of layers that perform convolution on an image that is input, one layer of which includes a filter layer in which a plurality of linear or nonlinear filters are incorporated, and convolution coefficients of the plurality of linear or nonlinear filters are predetermined.

  • Patent number: 5537552
    Abstract: An information reproducing apparatus for reproducing recorded data includes a buffer, a control device and a determining device. The buffer stores data blocks read out from a recording medium and includes first and second storage areas having respectively discontinuous storing and read addresses. The apparatus is controlled to execute in parallel a first process for storing the data blocks into the buffer and a second process for reading out the data blocks stored in the buffer to transfer the data blocks to a host apparatus. The determining device determines whether there are data in the first storage area to be transferred to the host apparatus by comparing a storing address in the buffer of the data which are being stored into the first storage area with a read address in the buffer of the data which are being read out from the first storage area. The first process is controlled so that a predetermined data block which has been read out from the recording medium is stored into the second storage area.
