UnverifiedRecovering 3D pose from a single ellipse has a two-solution ambiguity, where the same ellipse corresponds to two mirror-symmetric spatial orientations that cannot be distinguished from a single image contour alone79% similarUnverifiedDepth estimation, which recovers three-dimensional spatial information from two-dimensional images, is an ill-posed problem because there are infinitely many possible solutions for the mapping from 2D to 3D76% similarUnverifiedReconstructing 3D structure from a single 2D image is inherently an ill-posed problem, because a single viewpoint loses a great deal of depth and occlusion information.73% similar
