This process is hereafter referenced to as being the “external” process.

Abstract: In one implementation, KLT transform matrices are derived during the encoding or decoding process. In particular, the KLT transform matrices can be derived for either the primary transforming stage or the secondary transforming stage, or both. Because the KLT transform matrices can be derived at both the encoder and decoder sides, the KLT transform matrices do not need to be signaled in the bitstream. To derive the KLT transform matrix for a current block to be encoded or decoded, a template for the current block is defined, and is used to search in reconstructed regions multiple blocks with templates similar to the current template. Those multiple blocks are used to train the KLT transform matrix.

The machine-readable instructions, when executed by the processor, also cause the processor to display an image captured by the camera of the following vehicle on a display device of the lead vehicle.

Abstract: A system and method for limited rate context-based eye gaze encoding includes generating, based on an outward looking camera situated in a vehicle, a first video stream of a surrounding environment to a controller. The controller generates a scene description based on the first video stream and selects a corresponding scene from a predefined list of known scenes. Further, the controller, based on the selected corresponding scene, selects a codebook of encoding and decoding parameters from a plurality of predefined codebooks. Based on an inward looking camera situated in the vehicle, a second video stream of a face of a driver to an eye tracker controller is generated, where the eye tracker controller estimates a gaze direction of the driver. Encoded data comprising the estimated gaze direction of the driver is transmitted over a bandwidth limited channel to a decoder, based on the selected codebook, the encoded data.

Abstract: A system for executing a three-dimensional (3D) intraoperative scan of a patient is disclosed. A 3D scanner controller projects the object points included onto a first image plane and the object points onto a second image plane. The 3D scanner controller determines first epipolar lines associated with the first image plane and second epipolar lines associated with the second image plane based on an epipolar plane that triangulates the object points included in the first 2D intraoperative image to the object points included in the second 2D intraoperative image. Each epipolar lines provides a depth of each object as projected onto the first image plane and the second image plane. The 3D scanner controller converts the first 2D intraoperative image and the second 2D intraoperative image to the 3D intraoperative scan of the patient based on the depth of each object point provided by each corresponding epipolar line.
