CT Image Reconstruction - AAPM
reconstruction • Relates 2D FT of image to 1D FT of its projection • N.B. 2D FT is “k-space” of MRI One of the most fundamental concepts in CT image reconstruction if the “Central-slice” theorem. This theorem states that the 1-D FT of the projection of an object is the same as the values of the 2-D FT of the object along a line

arxiv.orgHuman Mesh Reconstruction (HMR): HMR is a task of reconstructing 3D human body shape, which is an active research topic in recent years. While pioneer works have demonstrated impressive reconstruction using various sen-sors, such as depth sensors [33,48] or inertial measurement units [20,54], researchers are exploring to use a monocular
