Alessandro Simoni

I am a Ph.D. Candidate at AImageLab at the University of Modena and Reggio Emilia, Italy.

My research activities are focused on Computer Vision and Deep Learning applied to Collaborative Robotic tasks, more precisely in topics like 3D Object Reconstruction and Human/Robot Pose Estimation. I work under the supervision of Prof. Roberto Vezzani.

In the first part of my Ph.D. I tackled the task of 3D Object Reconstruction. More recently, I've started working on robotic tasks, involving Pose Estimation and Grasping. Representative papers are highlighted.

Semi-Perspective Decoupled Heatmaps for 3D Robot Pose Estimation from Depth Maps
Alessandro Simoni, Stefano Pini, Guido Borghi, Roberto Vezzani
Under Review

Thanks to a novel 3D pose representation composed of two decoupled heatmaps, efficient deep networks from the 2D HPE domain can be adapted to accurately compute 3D joints locations in world coordinates. Moreover, depth maps are used to bridge the gap between synthetic and real data.

A multi-category mesh reconstruction framework infers the textured mesh of objects, learning category-specific priors in an unsupervised manner and obtaining smooth shapes with a dynamic mesh subdivision approach.
