    Abstract: In various examples, image data may be received that represents an image. Corner detection may be used to identify pixels that may be candidate corner points. The image data may be converted from a higher dimensional color space to a converted image in a lower dimensional color space, and boundaries may be identified within the converted image. A set of the candidate corner points may be determined that are within a threshold distance to one of the boundaries, and the set of the candidate corner points may be analyzed to determine a subset of the candidate corner points representative of corners of polygons. Using the subset of the candidate corner points, one or more polygons may be identified, and a filter may be applied to the polygons to identify a polygon as corresponding to a fiducial marker boundary of a fiducial marker.

    Abstract: A system and method are provided for a 3D modeling system with which an encoded video stream is produced. The system includes a content engine, an encoder, and a fixed function engine. The fixed function engine receives content information from the content engine. The fixed function engine produces encoder information from the content information. The encoder uses the encoder information to produce an encoded video stream having at least one of a higher quality and a lower bandwidth than a video stream encoded without the encoder information.

    Abstract: Real time content enhancement can be provided using a solution that is lightweight enough to operate on client devices, even for high resolution, high bitrate content. An enhancement process can include a neural network that upscales the content to a target resolution while also enhancing a visual quality of the content, such as to sharpen visual aspects of the content and reduce a presence of artifacts. Such an approach can enable compressed content to be transmitted in streams across a network, in order to conserve bandwidth and data transmission, while also enabling that content to be upscaled and enhanced at the client device in real time, such that a user or viewer can experience the content at, near, or above its intended or original visual quality.

    Abstract: A method for stereoscopically presenting visual content is disclosed. The method comprises identifying and distinguishing between a first type of content and a second type of content of a frame to be stereoscopically displayed. The method also comprises rendering the first type of content in a first left and a first right frame from a single perspective using a first stereoscopic rendering method. Further, the method comprises rendering the second type of content in a second left and a second right frame using a second, different stereoscopic method from two different perspectives. Additionally, the method comprises merging the first and second left frames and the first and second right frames to produce a resultant left frame and a resultant right frame. Finally, the method comprises displaying the resultant left frame and the resultant right frame for stereoscopic perception by a viewer.
