If the model is allowed to change its shape in time, this is referred to as non-rigid or spatio-temporal reconstruction. This imaging technique is not only widely available but is also, in contrast to more advanced 3D imaging methods like CT or MRI, considered a fast and inexpensive procedure. Image Reconstruction is generally an inverse problem, which helps to recover the original ideal image from its given bad version, such as one that is snowed by noise, blurred by atmospheric turbulence or that has some regions damaged. Guoyan Zheng, Weimin Yu, in Statistical Shape and Deformation Analysis, 2017. Motivation. Each object is annotated with a 3D bounding box.
