Abstract
A method of discriminative recovery of three-dimensional digital data of a target of interest in a cluttered or controlled environment. The method uses the traditional structure from motion (SFM) 3D reconstruction method on a video of a target of interest to track and extract 3D sparse feature points and relative orientations of the video frames. Desired 3D points are filtered from the 3D sparse feature points in accordance to a user input and a digital cutting tool. Segmented images are generated by separating the target of interest from the background scene in accordance to the desired 3D points. A dense 3D reconstruction of the target of interest is generated by inputting the segmented images and the relative orientations of the video frames.
