Simultaneous segmentation, estimation and analysis of articulated motion from dense point cloud sequence

Youngji Kim, Hwasup Lim, Sang Chul Ahn, Ayoung Kim

IROS 2016poster

In this paper, we present a unified approach for Expectation Maximization (EM) based motion segmentation, estimation and analysis from dense point cloud data. When identifying an underlying motion, literature mainly focuses on three related topics: motion segmentation, estimation and analysis. These…

Generalized Deformable Spatial Pyramid: Geometry-Preserving Dense Correspondence Estimation

Junhwa Hur, Hwasup Lim, Changsoo Park, Sang Chul Ahn

CVPR 2015poster

We present a Generalized Deformable Spatial Pyramid (GDSP) matching algorithm for calculating the dense correspondence between a pair of images with large appearance variations. The main challenges of the problem generally originate in appearance dissimilarities and geometric variations between imag…
