摘要： A camera of a ground-based information dispatch apparatus captures a blind-spot image, showing a region that is a blind spot with respect to a vehicle driver. A vehicle-mounted camera captures a forward-view image corresponding to the viewpoint of the driver, and the forward-view image is transmitted to the information dispatch apparatus together with vehicle position and direction information and camera parameters. Based on the received information, the blind-spot image is converted to a corresponding image having the viewpoint of the vehicle driver, and the forward-view image and viewpoint-converted blind-spot image are combined to form a synthesized image, which is transmitted to the vehicle.

摘要： Body-mounted cameras are used to accurately reconstruct the motion of a subject. Outward-looking cameras are attached to the limbs of the subject, and the joint angles and root pose that define the subject's configuration are estimated through a non-linear optimization, which can incorporate image matching error and temporal continuity of motion. Instrumentation of the environment is not required, allowing for motion capture over extended areas and in outdoor settings.

摘要： A relative pose between two cameras is determined by using input data obtained from the motion of subjects, such as pedestrians, between the fields of view of two cameras, determining trajectory information for the subjects, and computing homographies relating lines obtained from trajectories in the first image data to lines obtained from the trajectories in the second image data. The two fields of view need not overlap.

The facial layers include one or more parameters extracted from the received input. A facial expression for a second character and corresponding to the facial expression of the first character is generated, based on the facial layers and without defining any spatial correspondence between the first character and the second character.

摘要： Techniques are disclosed for augmenting hand-drawn animation of human characters with three-dimensional (3D) physical effects to create secondary motion. Secondary motion, or the motion of objects in response to that of the primary character, is widely used to amplify the audience's response to the character's motion and to provide a connection to the environment. These 3D effects are largely passive and tend to be time consuming to animate by hand, yet most are very effectively simulated in current animation software. The techniques enable hand-drawn characters to interact with simulated objects such as cloth and clothing, balls and particles, and fluids. The driving points or volumes for the secondary motion are tracked in two dimensions, reconstructed into three dimensions, and used to drive and collide with the simulated objects.
