Linear Shape Deformation Models with Local Support Using Graph-Based Structured Matrix Factorisation

Abstract: α = +[ PCA (global support) Our (local support) PCA (global support) Our (local support) PCA (global support)Our (local support)Global support factors of PCA lead to implausible body shapes, whereas the local support factors of our method give more realistic results. See our accompanying video for animated results. AbstractRepresenting 3D shape deformations by highdimensional linear models has many applications in computer vision and medical imaging. Commonly, using Principal Components Analysis a low-dimensio… Show more

“…Although for the horse dataset, the method [24] has an error equal to 29.6090 and 20.1994 in [21], 18.0624 in [23], 12.9605 in [25], and 7.3682 in [20], compared to 6.4412 in our work. It is clear that the obtained error rate is so reduced and the performance of a MA on the synthesised mesh allows to minimise the resolution without losing the initial data, reaching the control mesh.…”

“…Indeed, our deformation algorithm gives a good reconstructed object and is more performing as it has better quantitative reconstruction findings than the existing technique having lower reconstruction errors when enough components are employed. Visual results shown in [20, 21, 23, 25] did not deal intensively with large‐scale rotations and could not reform possible models in such cases. Nevertheless, Wang et al .…”

“…Deformation representation is important for effective data-driven deformation. Euclidean coordinates are the most straightforward way [36], [43], although with obvious limitations for rotations. More effective deformation gradients are used to represent shape deformations [5], [37], which still cannot handle large rotations.…”
