Estimation of Human Body Shape in Motion with Wide Clothing

Estimation of Human Body Shape in Motion with Wide Clothing

European Conference on Computer Vision, 2016
Jinlong Yang, Jean-Sébastien Franco, Franck Hétroy-Wheeler, and Stefanie Wuhrer

Estimating 3D human body shape in motion from a sequence of unstructured oriented 3D point clouds is important for many applications. We propose the first automatic method to solve this problem that works in the presence of loose clothing. The problem is formulated as an optimization problem that solves for identity and posture parameters in a shape [...]


Real-time demo with textures

We added textures to the meshes in the real-time demo. The textures are built from the views of 60 cameras. This requires to compress 60 4Mpix images to less than 10 MB so that the NIC and GPU of the rendering machine do not get overloaded.

Therefore, the textures are clipped using the silhouette mask that we have available anyway, and compressed in a hardware format supported by the GPU (DXT1). Rate control is applied to make sure that the total [...]


Kinovis at Experimenta – Grenoble, 08-10/10/2015

ANIMO ( A#1trailer 2014 et A#2maquette 2015) from gwendaline bachini on Vimeo.

The prototype of A#2 willl be displayed at EXPERIMENTA 2015, in Grenoble.

A#2 is an interactive installation created by Gwendaline Bacchini with the help of 4DView Solution and SIP Conseil, as well as the Morpheo Team at Inria Grenoble, for the Creamove project .

This installation uses data produced in Kinovis and shows an amazing example of how 4D data can change the [...]


3D reconstruction in real time

The Kinovis studio was recently extended to perform real-time 3D reconstruction. The previous version of the platform, Grimage, did this, but at a much smaller scale (up to 12 cameras). Kinovis replaces the algorithm based on EPVH with a more scalable version based on QuickCSG.

Each of the 60 cameras streams its video to one of the 17 acquisition machines. The machine extracts the silhouette locally and computes its contour. Then a 3-stage algorithm (with 2 n-to-n [...]
