  • Publication number: 20210287395
    Abstract: An information processing system includes a storage device that stores therein a trained model, and a processor. The trained model is trained to output a position and shape of an object in a training image based on training data. The training data is data in which the training image is provided with an annotation indicating the position and shape of the object. The training image is an image captured with an angle of view including the object whose position and shape are not clearly displayed in an image. The processor executes detection processing on a detection image to output detected information indicating the position and shape of the object. The processor then causes a display device to display the detected information superimposed on the detection image.

  • Publication number: 20210183076
    Abstract: A tracking device includes a processor including hardware, and the processor sets a start frame, extracts multiple representative points of a contour of a tracking target, tracks the extracted multiple representative points, performs outlier determination based on an interrelationship of the tracked multiple representative points, performs a process of removing an outlier representative point determined to be an outlier, and extracts new representative points based on multiple representative points after the process of removing the outlier representative point when a given condition is met.

  • Publication number: 20210174518
    Abstract: A tracking device includes a processor including hardware. The processor is configured to: set a start frame and an end frame in a video including multiple frames; perform forward tracking in frames subsequent to the start frame based on a region of a tracking target in the start frame; perform backward tracking in frames previous to the end frame based on a region of the tracking target in the end frame; and generate a combined mask image by combining a forward mask image based on the forward tracking with a backward mask image based on the backward tracking.

  • Publication number: 20200217716
    Abstract: An optical measurement device includes: an optical sensor that detects pulsed signal light and that outputs a detection signal formed of an exponential-function response; an A/D converter that samples the detection signal output from the optical sensor and that converts the detection signal into a digital signal; and a processor comprising hardware, the processor being configured to subject the digital signal output from the A/D converter to inverse transformation by using a multiple diagonal matrix, thus calculating an estimated pulse of the signal light.

  • Patent number: 10631826
    Abstract: A medical apparatus includes a model-image generating section configured to generate a model image obtained by modeling a shape of an inside of a subject, a coordinate calculating section configured to detect a three-dimensional position of a feature point of the inside of the subject, set a polar coordinate on the basis of a position of the feature point, and calculate an arbitrary three-dimensional position of the inside of the subject according to the polar coordinate, and an image generating section configured to show the arbitrary three-dimensional position of the inside of the subject on the model image on the basis of one angle component among components of the polar coordinate calculated by the coordinate calculating section and a value obtained by correcting the one angle component according to another angle component.
