Abstract: Example implementations include a method, apparatus and computer-readable medium of computer vision configured for person classification, comprising receiving, during a first period of time, a plurality of image frames of an environment, identifying images of persons from each frame of the plurality of image frames, and determining a respective vector representation of each of the images. The implementations include generating a probability distribution indicative of a likelihood of a particular vector representation appearing in the plurality of image frames and identifying an associate vector representation by sampling the probability distribution using a probability model. The implementations include determining an input vector representation of an input image identified in an image frame depicting a person and received during a second period of time. The implementations include comparing the input vector representation with the associate vector representation and classifying, based on the comparison, the person in the input image as an associate.

Abstract: Systems and methods for medical training are provided. In some embodiments, systems and methods use computer generated simulated patients through augmented reality. In some embodiments, systems and methods enable medical training that allows a user to interact with the simulated patient which provides simulated visual, audio, or other user perceivable reactions. In some embodiments, hand tracking technology is used in a unique way to detect collisions with a virtual object to result in naturally appearing physical exam maneuvers to simulate the physical examination (e.g., auscultation, percussion, palpation stages of a physical examination) of the simulated patient.

Abstract: In a person tracking system, a calculation processing means performs processing for detecting a first person from an image, and calculates a first feature vector representing a feature of the detected first person. A data transmission processing means acquires a hash value corresponding to a key generated based on information relating to the first feature vector, and stores feature data including the first feature vector and the key in a storage area of an external device determined based on the acquired hash value. A determination processing means determines whether or not the first person represented by the first feature vector included in the feature data read from the external device and a second person registered in advance are the same person. A tracking processing means tracks the first person as a tracking target, when it is determined that the first person and the second person are the same person.

Abstract: A text entry process for an Augmented Reality (AR) system. The AR system detects, using one or more cameras of the AR system, a start text entry gesture made by a user of the AR system. During text entry, the AR system detects, using the one or more cameras, a symbol corresponding to a fingerspelling sign made by the user. The AR system generates entered text data based on the symbol and provides text in a text scene component of an AR overlay provided by the AR system to the user based on the entered text data.

Abstract: A method of human pose estimation, including, receiving an image frame, extracting in at least a first stage a first stage image feature based on the image frame, extracting in at least a second stage a second stage image feature based on the first stage image feature, extracting in at least a subsequent stage a subsequent stage image feature based on the second stage image feature, up-sampling the subsequent stage image feature, up-sampling the second stage image feature, concatenating the first stage image feature, the up-sampled second stage image feature and the up-sampled subsequent stage image feature and outputting a feature map based on an output of the concatenation.

Abstract: The disclosure is generally directed to systems and methods for guiding an individual to an electrical power outlet in a vehicle. An example method executed by a processor of an electrical power outlet controller in a vehicle includes determining that an individual is seeking an electrical power outlet provided on the vehicle, selecting a first electrical power outlet from a plurality of electrical power outlets provided on the vehicle, and providing location information of the first electrical power outlet. The location information may be provided in various forms such as in the form of an audio signal (a beeping sound produced by a beeper, for example), a visual indication (a light source illuminating the electrical power outlet, for example) an audible instruction (navigation assistance provided via a speaker, for example), a graphical indication (navigation assistance via a personal device), and/or a text message (navigation assistance via a personal device).

Abstract: An autonomous vehicle can include a horn; a sensor(s) configured to capture images; and one or more processors. The one or more processors can be configured to receive a sequence of images from the sensor(s), the sequence of images captured by the sensor(s) as the autonomous vehicle was moving; execute a machine learning model using the sequence of images as input to detect a human inside a second vehicle or in the surrounding environment of the autonomous vehicle depicted within the sequence of images; determine, based on the detection of the human inside the second vehicle or in the surrounding environment of the autonomous vehicle within the sequence of images, the human is depicted performing a defined arm gesture within the sequence of images; and activate the horn responsive to the determination that the human is depicted performing the defined arm gesture within the sequence of images.

Abstract: A pose calculating apparatus and method are provided. The pose calculating apparatus receives a plurality of real-time images and a plurality of inertial measurement parameters corresponding to at least one inertial sensor worn by a user. The pose calculating apparatus determines a pose calculating mode corresponding to each of a plurality of body regions of the user based on the real-time images and the inertial measurement parameters, wherein the pose calculating mode corresponds to a static mode or a motion mode. The pose calculating apparatus calculates a pose corresponding to each of the body regions based on the pose calculating mode corresponding to each of the body regions.
