Parts and Relations in Young Children's Shape-Based Object Recognition

Parts and Relations in Young Children's Shape-Based Object Recognition.

The ability to recognize common objects from sparse information about geometric shape emerges during the same period in which children learn object names and object categories. Hummel and Biederman's (1992) theory of object recognition proposes that the geometric shapes of objects have two components-geometric volumes representing major object parts, and the spatial relations among those parts....

Object Recognition Using Appearance-Based Parts and Relations

The recognition of general three-dimensional objects in cluttered scenes is a challenging problem. In particular, the design of a good representation suitable to model large numbers of generic objects that is also robust to occlusion has been an stumbling block in achieving success. In this paper, we propose a representation using appearance-based parts and relations to overcome these problems....

Shape Based Object Detection and Recognition in

Shape Based Object Detection and Recognition in Silhouettes and Real Images Xingwei Yang DOCTOR OF PHILOSOPHY Temple University, March, 2011 Dr. Longin Jan Latecki, Chair Shape is very essential for detecting and recognizing objects. It is robust to illumination, color changes. Human can recognize objects just based on shapes, thus shape based object detection and recognition methods have been ...

Shape-Primitive Based Object Recognition and Grasping

Grasping objects from unstructured piles is an important, but difficult task. We present a new framework to grasp objects composed of shape primitives like cylinders and spheres. For object recognition, we employ efficient shape primitive detection methods in 3D point clouds. Object models composed of such primitives are then found in the detected shapes with a probabilistic graph-matching tech...
