Using manipulation primitives for brick sorting in clutter
Megha Gupta,Gaurav S. Sukhatme +1 more
TL;DR: A robust pipeline is presented that combines perception and manipulation to accurately sort Duplo bricks by color and size and uses two simple motion primitives to manipulate the scene in ways that help the robot to improve its perception.
Journal ArticleDOI
Using Manipulation Primitives for Object Sorting in Cluttered Environments
TL;DR: A robust pipeline that combines perception and manipulation to accurately sort objects by some property is presented, which results in the ability to sort cluttered object piles accurately.
Journal ArticleDOI
Shape and texture-based radiomics signature on CT effectively discriminates benign from malignant renal masses.
Felix Y. Yap,Bino Varghese,Steven Cen,Darryl Hwang,Xiaomeng Lei,Bhushan Desai,Christopher Lau,Lindsay Yang,Austin Fullenkamp,Simin Hajian,Marielena Rivas,Megha Gupta,Brian D. Quinn,Manju Aron,Mihir M. Desai,Monish Aron,Assad A. Oberai,Inderbir S. Gill,Vinay Duddalwar +18 more
TL;DR: Current radiomics research is heavily weighted towards texture analysis, but quantitative shape metrics should not be ignored in their potential to distinguish benign from malignant renal tumors, and future radiomics platforms powered by machine learning should harness both shape and texture metrics.
Journal ArticleDOI
Quantitative Contour Analysis as an Image-based Discriminator Between Benign and Malignant Renal Tumors.
Felix Y. Yap,Darryl Hwang,Steven Cen,Bino Varghese,Bhushan Desai,Brian D. Quinn,Megha Gupta,Nieroshan Rajarubendra,Mihir M. Desai,Manju Aron,Gangning Liang,Monish Aron,Inderbir S. Gill,Vinay Duddalwar +13 more
TL;DR: Computerized image analysis is feasible using shape descriptors that otherwise cannot be visually assessed and used without quantification, but encompassing all 3 planar dimensions to characterize tumor contour can achieve a more comprehensive evaluation.
Proceedings ArticleDOI
Interactive environment exploration in clutter
TL;DR: This paper investigates the idea of exploring a small, bounded environment by prehensile and non-prehensile manipulation of the objects it contains by presenting an implementation on the PR2 robot and using it for object search in clutter.
