Gemmechu Hassena

I am a CS PhD student at Cornell University working in the intersection of ML, CV and Graphics, advised by Bharath Hariharan and Steve Marschner. Prior to Cornell I earned my Bachelor's in Software Engineering from Addis Ababa University, Ethiopia. I have worked as a research intern at INRIA, Ecole Polytechnique with Maks Ovsjanikov. and at Univeristy of Michigan with David Fouhey on a Computer vision, Graphics and machine learning projects.

Research
ObjectCarver: Semi-automatic segmentation, reconstruction and separation of 3D objects

How can we separate objects in a scene without a segmentation mask? Given multi-view images and point clicks in a single view, ObjectCarver will generate a mask, propagate it to other views, reconstruct the 3D surface, and separate the individual objects in the scene.

Quantifying Bird Skeletons
Zhizhuo Zhou , Gemmechu Hassena, Brian C. Weeks, David F. Fouhey
CV4Animals Workshop, CVPR 2021
[PDF] [Bibtex]

We introduced a dataset and system for measuring skeletal traits from museum specimens, which speeds up skeleton measurement by 15x. This research helped Ecologists in their study of how global warming causes the size of birds to shrink

Projects
Scene understanding using humans as a ruler
Gemmechu Hassena, Chris Rockwell, David Fouhey
AURA, Sep 2020
[Video]

Monocular depth estimation, we developed a model that estimates depth and floor of a scene from RGB image, by using people's height as the reference.
