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 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.
