  • Patent number: 11875547
    Abstract: An image processing apparatus according to an embodiment includes a processor. The processor acquires a classification result of classifying each of a plurality of regions set in a processing target image into one of a plurality of predetermined classes. The processor converts multidimensional data corresponding to each of the plurality of regions set in the image into low-dimensional data. The processor causes a display image including one or more regions to be displayed together with a plotted diagram including a plurality of plot points having different colors or patterns applied according to the classification result to the low-dimensional data in each of the plurality of regions, and in a case where an instruction for selecting a selected point from among the plot points is issued, the processor performs a discriminative display causing the selected point and a region corresponding to the selected point in the display image to be visually identifiable.

  • Patent number: 11722289
    Abstract: In a case where signals branched from a single reference signal source are transmitted via a plurality of cables, a phase synchronization circuit can be used to stabilize a phase of a signal to be outputted from each cable. However, the phases of signal to be outputted from each cable is affected by combination of a length of each cable and an amount of delay caused by feedback control, so that phases of synchronization signals to be outputted from a plurality of transmission paths are not always the same as each other. In the present invention, since a frequency multiplier that multiplies a frequency of a signal outputted from each transmission path by an even number is provided for a phase synchronization circuit, the phases of the synchronization signals to be outputted from the transmission paths are aligned even when signals are branched from one reference signal.

  • Patent number: 10749233
    Abstract: As a layout requirement imposed on an in-phase corporate-feed circuit, there is provided only a layout requirement to equalize the electric length of a transmission line (4) between one of N T-branch units (6) which is m-th when counted from a start point of a path A, and another one of the T-branch units (6) which is (m+1)-th when counted from the start point of the path A, to that of a transmission line (8) between one of N T-branch units (10) which is m-th when counted from an end point of a path B, and another one of the T-branch units (10) which is (m+1)-th when counted from the end point of the path B. Therefore, the in-phase corporate-feed circuit can be formed in a space smaller than that in which its circuit configuration of tournament type is formed, and downsizing of the circuit size can be achieved.

  • Patent number: 10585169
    Abstract: A signal generating circuit includes a control voltage setting unit (CVSU) configured to set a control voltage for a chirp signal using voltage-frequency characteristics indicating characteristics of an output frequency versus voltage; a VCO configured to alter the frequency of its output signal by the control voltage; a quadrature demodulator configured to perform quadrature demodulation of the output signal of the VCO to generate an inphase signal and a quadrature signal orthogonal to each other; and a frequency detector configured to detect the frequency of the output signal of the VCO on the basis of the inphase signal and quadrature signal. The CVSU corrects the control voltage by using the voltage-frequency characteristics derived from relationships between the control voltage and the frequency of the output signal of the VCO. The VCO generates the chirp signal based on the control voltage corrected by the CVSU.

  • Patent number: 10373028
    Abstract: According to an embodiment, a pattern recognition device is configured to divide an input signal into a plurality of elements, convert the divided elements into feature vectors having the same dimensionality to generate a set of feature vectors, and evaluate the set of feature vectors using a recognition dictionary including models corresponding to respective classes, to output a recognition result representing a class or a set of classes to which the input signal belongs. The models each include sub-models each corresponding to one of possible division patterns in which a signal to be classified into a class corresponding to the model can be divided into a plurality of elements. A label expressing a model including a sub-model conforming to the set of feature vectors, or a set of labels expressing a set of models including sub-models conforming to the set of feature vectors is output as the recognition result.
