Abstract: An angled axis machine vision system having two cameras angled with respect to roil axis. Provides advantages of horizontal alignment between two cameras and eliminates problem of utilizing horizontal/vertical lines in the environment for distance calculations when lines arc parallel or close to parallel to axis between camera centers. With camera centers angled about roll axis, horizontal/vertical lines in environment appear angled with respect to horizon, enabling accurate distance calculations. With the cameras angled about roll, lines in the environment may line up parallel to the axis between camera centers, but these instances are rare in real world environments. May be rotatably mounted in the roll axis wherein two sets of pictures from each of the cameras may either he utilized: the two sets compared for the number of parallel lines parallel to axis between camera centers and the set of pictures with least parallel lines used for distance calculations.
Abstract: Methods and apparatuses are provided for achieving improved video coding efficiency through the use of Motion Vector Predictors (MVPs) for the encoding or decoding of motion parameters within the calculation of the motion information in B pictures and/or P pictures. Certain exemplary methods and apparatuses selectively apply temporal and/or spatial prediction. Rate Distortion Optimization (RDO) techniques are also applied in certain methods and apparatuses to further help improve coding efficiency.

Abstract: Digital binocular fusing apparatus places a primary image in registration with a lenticular lens to produce a secondary 3D image from the primary image. The apparatus includes a lens array, a display mounted behind the lens array and including a primary image and reference marks, a primary image orientation adjustment system for receiving registration adjustment signals to adjust the position of the primary image and the reference marks, a sensor to detect the position of the reference marks and generate position identification signals, and, a registration control for receiving the position identification signals, determining if the primary image is in registration with the lens array, and, if necessary, generating registration adjustment signals and transmitting the registration adjustment signals to the primary image orientation adjustment system.
