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.

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.

Abstract: Systems, devices, and methods for planning an endoscopic tissue acquisition procedure for acquiring tissue from an anatomical target are disclosed. An endoscopic system comprises a steerable elongate instrument and a processor. The steerable elongate instrument can be positioned and navigated in a patient anatomy and acquire tissue from an anatomical target via a biopsy tool associated with the steerable elongate instrument. The processor can receive an image of the anatomical target, apply the received image to a trained machine-learning (ML) model to determine a tissue acquisition plan that includes a recommended biopsy tool and operational parameters for navigating the steerable elongate instrument or maneuvering the recommended biopsy tool. The tissue acquisition plan can be presented to a user, or used to facilitate a robot-assisted tissue acquisition procedure.

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.

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.
