Abstract: This disclosure relates to method and system for generating tightest revolve envelope for a Boundary representation (B-rep) Computer-Aided Design (CAD) model. The method includes receiving a 2-dimensional (2D) point cloud within an XY-plane corresponding to each of a plurality of faces of the B-rep CAD model within an XYZ-space. The method further includes, for each of the plurality of faces, determining a concave hull shape for the 2D point cloud through a concave hull algorithm. The method further includes combining the concave hull shape corresponding to each of the plurality of faces of the B-rep CAD model through at least one of a Boolean operation and a stitching operation to obtain a tightest revolve profile of the B-rep CAD model. The method further includes revolving the tightest revolve profile about X-axis of the XYZ-space to obtain a tightest revolve envelope corresponding to the B-rep CAD model.

Abstract: An electronic device having a touch-screen display detects a first input on the display while displaying a first user interface on the display. In response to detecting the first input on the display, the device enters a flashlight mode. Entering the flashlight mode includes replacing the first user interface with a first flashlight user interface. The first flashlight user interface has a first total lumen output and a first luminance that is substantially uniform over the display. The device determines whether brightness change criteria are met, and in accordance with a determination that the brightness change criteria are met, displays a second flashlight user interface having a second total lumen output greater than the first total lumen output and a second luminance that is substantially uniform over the display.

Abstract: A method for producing network sites, in particular websites, offers real immersion in the sites (in the manner of video games) with intuitive and fluid navigation that does not require a means for directing the avatar, allows selective referencing by a search engine of objects contained on the site, as well as providing improved access security. A simple mechanical control means (arrow keys on a keyboard, mouse without click buttons, joystick formed by a handle on a base with push buttons) or virtual control means (arrow-based computer representation, system for the detection of a movement of the hand, eye, etc., accelerometer remote control, etc.) can be used to direct the avatar. The method allows the movements of the avatar to be interpreted, such as a simple walk through the site or a command to navigate to another space on the site (same URL) or to another site (different URL).

Abstract: A calibration platform may obtain measurements for aligning a real-world coordinate system and a display coordinate system. For example, the calibration platform may display, via an optical see-through head-mounted display (OST-HMD), a three-dimensional virtual object and receive, from a positional tracking device, information that relates to a current pose of a three-dimensional real-world object to be aligned with the three-dimensional virtual object. The calibration platform may record a three-dimensional position of a plurality of points on the three-dimensional real-world object based on the current pose of the three-dimensional real-world object, based on an indication that the plurality of points on the three-dimensional real-world object respectively corresponds with a plurality of points on the three-dimensional virtual object.

Abstract: A smart, human-centered technique that uses artificial intelligence and mixed reality to accelerate essential tasks of the inspectors such as defect measurement, condition assessment and data processing. For example, a bridge inspector can analyze some remote cracks located on a concrete pier, estimate their dimensional properties and perform condition assessment in real-time. The inspector can intervene in any step of the analysis/assessment and correct the operations of the artificial intelligence. Thereby, the inspector and the artificial intelligence will collaborate/communicate for improved visual inspection. This collective intelligence framework can be integrated in a mixed reality supported see-through headset or a hand-held device with the availability of sufficient hardware and sensors. Consequently, the methods reduce the inspection time and associated labor costs while ensuring reliable and objective infrastructure evaluation.

Embodiments of the present disclosure encode features of a source image to obtain a source appearance encoding that represents inherent attributes of a face in the source image; encode features of a target image to obtain a target non-appearance encoding that represents contextual attributes of the target image; combine the source appearance encoding and the target non-appearance encoding to obtain combined image features; and generate a modified target image based on the combined image features, wherein the modified target image includes the inherent attributes of the face in the source image together with the contextual attributes of the target image.

Abstract: Moving images of a space, which includes objects 34 and 35 of a display target, as viewed from reference points are created in advance as reference images, and they are combined in response to actual positions of the points of view to draw a moving image. When the object 35 is displaced as indicated by an arrow mark in the space, reference points of view 30a to 30e are fixed as depicted in (a). Alternatively, the reference points of view are displaced in response to the displacement like reference points of view 36a to 36e in (b). Then, the moving images from the reference points of view are generated as the reference images.

Abstract: An image processing system comprising: a computer readable medium and at least one processor configured to provide a machine learning architecture for image processing. In particular, keyframes are selected for modification by a visual artist, and the modifications are used for training the machine learning architecture. The modifications are then automatically propagated to remaining frames requiring modification through interpolation or extrapolation through processing remaining frames through the trained machine learning architecture. The generated modified frames or frame portions can then be inserted into an original video to generate a modified video where the modifications have been propagated. Example usages include automatic computational approaches for aging/de-aging and addition/removal of tattoos or other visual effects.

Abstract: The current document is directed to methods and systems that provide an automated augmented-reality facility for determining whether or not personal items and luggage meet airline requirements. In one implementation, a semi-transparent three-dimensional image generated from a model of a personal item or luggage item of the maximum dimensions allowed by an airline is displayed to a user, on a user device that includes a camera, within an electronic image of the real scene encompassed by the field of view of the camera. The user can then position a real personal item or luggage item at a point in space corresponding to the apparent position of the virtual image of the model and compare the dimensions of the real personal item or luggage item to the dimensions of the semi-transparent model volume in order to determine whether or not the real personal item or luggage item meets airline size requirements.
