Abstract: An intuitive interface may allow users of a computing device (e.g., children, etc.) to create imaginary three dimensional (3D) objects of any shape using body gestures performed by the users as a primary or only input. A user may make motions while in front of an imaging device that senses movement of the user. The interface may allow first-person and/or third person interaction during creation of objects, which may map a body of a user to a body of an object presented by a display. In an example process, the user may start by scanning an arbitrary body gesture into an initial shape of an object. Next, the user may perform various gestures using his body, which may result in various edits to the object. After the object is completed, the object may be animated, possibly based on movements of the user.

Abstract: Implementations of the subject matter described herein relate to mixed reality object rendering based on ambient light conditions. According to the embodiments of the subject matter described herein, while rendering an object, a wearable computing device acquires light conditions of the real world, thereby increasing the reality of the rendered object. In particular, the wearable computing device is configured to acquire an image of an environment where the wearable computing device is located. The image is adjusted based on a camera parameter used when the image is captured. Subsequently, ambient light information is determined based on the adjusted image. In this way, the wearable computing device can obtain more real and accurate ambient light information, so as to render to the user an object with enhanced reality. Accordingly, the user can have a better interaction experience.

Abstract: In accordance with implementations of the subject matter described herein, there is provided a solution of lighting estimation. In the solution, an input image about a real object and a depth map corresponding to the input image are obtained. A geometric structure of the scene in the input image is determined based on the depth map. Shading and shadow information on the real object caused by a light source in the scene is determined based on the determined geometric structure of the scene. Then, a lighting condition in the scene caused by the light source is determined based on the input image and the shading and shadow information. The virtual object rendered using the lighting condition obtained according to the solution can exhibit a realistic effect consistent with the real object.

Abstract: The present invention provides a method for preparing a transparent free-standing titanium dioxide nanotube array film. In the method, with the titanium foil as a substrate, the titanium dioxide nanotube array film is obtained by anode oxidation on the surface of the titanium foil. Upon high temperature annealing, the titanium dioxide nanotube array film naturally falls off to obtain the transparent free-standing titanium dioxide nanotube array film. The method according to the present invention features simple operations, saves time and cost. With the method, a completely strippable titanium dioxide nanotube array film may be prepared, and in addition, morphology of the titanium dioxide nanotube is not damaged. The free-standing and complete titanium dioxide nanotube array film facilitates transfer and post-treatment, has the feature of transparency and may be in favor of the applications to the studies such as photocatalysis and the like.

Abstract: In various examples, a sequential deep neural network (DNN) may be trained using ground truth data generated by correlating (e.g., by cross-sensor fusion) sensor data with image data representative of a sequences of images. In deployment, the sequential DNN may leverage the sensor correlation to compute various predictions using image data alone. The predictions may include velocities, in world space, of objects in fields of view of an ego-vehicle, current and future locations of the objects in image space, and/or a time-to-collision (TTC) between the objects and the ego-vehicle. These predictions may be used as part of a perception system for understanding and reacting to a current physical environment of the ego-vehicle.

Next, based on the first geometric feature and the ground-truth normal, a mapping from the first geometric feature to the ground-truth normal of the first facet is determined for denoising the mesh.
