"The abolishment of pain in surgery is a chimera. It is absurd to go on seeking it...knife and pain are two words in surgery that must forever be associated in the consciousness of the patient."
Dr. Alfred Velpeau, French surgeon ; 1839

The scene reconstruction system includes a motion parameter generator, a dense depth map generator, and a scene reconstructor. The motion parameter generator generates in response to gradients in image intensity values at respective points in a first view and temporal derivatives of image intensity values as between second and third views and the first view values for motion parameters representing as between a first view recordation location for the first view, and view recordation locations for the second and third views. The dense depth map generator generates a dense depth map in response to the values for the motion parameters, gradients in image intensity values at respective points in a first view and temporal derivatives of image intensity values as between second and third views and the first view, the dense depth map representing for each point in the first view the depth of a corresponding point in the scene. The scene reconstructor uses the dense depth map in generating a reconstruction of the at least one feature. | InventorsAssigneeApplicationNo. 016701 filed on 01/30/1998US Classes:345/419, Three-dimension382/107, Motion or velocity measuring382/154, 3-D or stereo imaging analysis382/236, Interframe coding (e.g., difference or motion detection)382/285Mapping 2-D image onto a 3-D surfaceField of Search345/419, Three-dimension382/107, Motion or velocity measuring382/154, 3-D or stereo imaging analysis382/236, Interframe coding (e.g., difference or motion detection)382/285Mapping 2-D image onto a 3-D surfaceExaminersPrimary: Powell, Mark R.Assistant: Sealey, Lance W.
