摘要： The shape of a three-dimensional object is determined from uncalibrated stereo images by first determining the projection of the point on a reference plane. The distance of each point from the reference plane is obtained by a technique that makes use of a calibration based on two known points visible in each camera's field of view. The method requires only one high precision measurement, which is the depth of the two calibration points from a reference plane. These may be supplied in a setup apparatus thereby avoiding the need for a user to make measurements. The rest of the required calibration data may be derived directly from the images of the cameras.

摘要： A monocular input image is transformed to give it an enhanced three dimensional appearance by creating at least two output images. Foreground and background objects are segmented in the input image and transformed differently from each other, so that the foreground objects appear to stand out from the background. Given a sequence of input images, the foreground objects will appear to move differently from the background objects in the output images.

摘要： The invention is embodied in a process for synthesizing a new image representing a new viewpoint of a scene from at least two existing images of the scene taken from different respective viewspoints. The process begins by choosing a planar surface visible in the at least two of the existing images and transforming the at least two existing images relative to one another so as to bring the planar surface into perspective alignment in the at least two existing images, and then choosing a reference frame and computing parallax vectors between the two images of the projection of common scene points on the reference frame. Preferably, the reference frame comprises an image plane of a first one of the existing images. Preferably, the reference frame is co-planar with the planar surface. In this case, the transforming of the existing images is achieved by performing a projective transform on a second one of the existing images to bring its image of the planar surface into perspective alignment with the image of the planar surface in the first existing image. Preferably, the image parameter of the new view comprises information sufficient, together with the parallax vectors, to deduce: (a) a trifocal ratio in the reference frame and (b) one epipole between the new viewpoint and one of the first and second viewpoints.
