Object Extraction using Segmentation ECE 847 Final Project Bryan Willimon
Overview • Background of Project • Main Idea and Focus • Drawbacks and Obstacles • Results • Conclusion/Future Work
Background • Current Research Project • Using computer vision to grab an unknown object from within a pile given a target item • Unknown = no previous knowledge of object • Working with PUMA arm in EIB • Previous projects have achieved similar results but with known surroundings and known objects (STAIR)
Main Idea • Extract an unknown object using various types of segmentation working together • Graph Segmentation and Lucas-Kanade • Graph Segmentation breaks image into many regions • Largest region (not touching a border) is determined to be object on top
Main Idea (cont.) • Determine centroid of the object to be the point of grasping (for 2D image) • Use Lucas-Kanade to give feature points in the whole image • Only track the feature points on current object • Continue tracking until all points are gone and repeat process until target is found
Drawbacks and Obstacles • Drawbacks • Graph Segmentation is slow • Only using 2D image for grasping • Obstacles • Find and use a faster algorithm • Grasping a 3D object requires 3D modeling and/or motion • Also check if any other objects will be damaged in any way once current item is being moved
Conclusion/Future Work • Results provide a way to extract an unknown object from a pile • Explore other segmentation algorithms and find something faster • Using color and/or clustering • Work on grasping 3D objects
