Various embodiments are directed to systems and methods for determining whether an individual uses proper posture to perform a job duty/task. For example, systems may determine whether an individual utilizes proper posture when lifting a heavy item from a floor. Accordingly, various embodiments comprise an image capture device and a central computing entity configured to receive item information/data for an item to be moved by an individual and to determine whether the item information/data satisfies one or more image collection criteria. Upon determining the item information/data satisfies one or more of the image collection criteria, the computing entity may activate an image capture device to collect image information/data of individuals performing the job duty/task, to compare collected image information/data against a plurality of reference images, and to determine whether the collected image information/data is indicative of the individual performing the job duty/task according to proper posture considerations.

Vision-assist devices and methods for calibrating a position of a vision-assist device worn by a user are disclosed. In one embodiment, a method of calibrating a vision-assist device includes capturing a calibration image using at least one capturing device of the vision-assist device, obtaining at least one attribute of the calibration image, and comparing the at least one attribute of the calibration image with a reference attribute. The method further includes determining an adjustment of the at least one image sensor based at least in part on the comparison of the at least one attribute of the calibration image with the reference attribute, and providing an output corresponding to the determined adjustment of the vision-assist device.

An information processing apparatus includes an imaging apparatus that irradiates reference light in a predetermined wavelength band to a subject and captures reflection of the reference light from the subject to acquire data of captured images including a polarized image in multiple bearings (S30). Based on the polarized image, the imaging apparatus acquires a polarization degree image representing a distribution of polarization degrees (S32). The imaging apparatus extracts a region whose polarization degree falls within a predetermined range of polarization degrees as an image of the subject having a predetermined material (S34). The imaging apparatus performs relevant processing on the subject image to generate output data and outputs the generated data (S36).

A system for executing a three-dimensional (3D) intraoperative scan of a patient is disclosed. A 3D scanner controller projects the object points included onto a first image plane and the object points onto a second image plane. The 3D scanner controller determines first epipolar lines associated with the first image plane and second epipolar lines associated with the second image plane based on an epipolar plane that triangulates the object points included in the first 2D intraoperative image to the object points included in the second 2D intraoperative image. Each epipolar lines provides a depth of each object as projected onto the first image plane and the second image plane. The 3D scanner controller converts the first 2D intraoperative image and the second 2D intraoperative image to the 3D intraoperative scan of the patient based on the depth of each object point provided by each corresponding epipolar line.

A device for determining normalized occupancy of one or more spaces in a building is disclosed. The device includes a memory and a processor coupled to the memory. The processor is configured to: poll one or more people counting sensors associated with access points to a defined region of the building to obtain counts data from the one or more people counting sensors for a specified time period and historical calibration data for the one or more people counting sensors; and process the counts data and the historical calibration data to determine a normalized occupancy of the defined region during the specified time period.

Images may be captured by a moving image capture device. A reference image and a background image may be selected from the images. The reference image may include depiction of an object, with the object blocking view of the background. The background image may include depiction of the background blocked by the object in the reference image. An object layer may be generated by segmenting the depiction of the object from the reference image. A background layer may be generated by combining the depiction of the background in the background image with the reference image. The background layer may be blurred and combined with the object layer to generate a panning image.

The various embodiments described herein include methods, devices, and systems for providing event alerts. In one aspect, a method includes: (1) obtaining a video feed, the video feed comprising a plurality of images; and, (2) for each image, analyzing the image to determine whether the image includes a person, the analyzing including: (a) determining that the image includes a potential instance of a person by analyzing the image at a first resolution; (b) in accordance with the determination that the image includes the potential instance, denoting a region around the potential instance; (c) determining whether the region includes an instance of the person by analyzing the region at a second resolution, greater than the first resolution; and (d) in accordance with a determination that the region includes the instance of the person, determining that the image includes the person.

Disclosed herein is a system and method directed to object tracking and metric generation using a plurality of cameras. The system includes the plurality of cameras disposed around a playing surface in a mirrored configuration, where the plurality of cameras are time-synchronized. The system further includes logic that, when executed by a processor, causes performance of operations including: obtaining a sequence of images from the plurality of cameras, continuously detecting an object in image pairs at successive points in time, wherein each image pair corresponds to a single point in time, continuously determining a location of the object within the playing space through triangulation of the object within each image pair, detecting a player and the object within each image of a subset of image pairs of the sequence of images, identifying a sequence of interactions between the object and the player, and storing the sequence of interactions.
