TLDR

This paper presents a comparative study and survey of model-based object-recognition algorithms for robot vision. The goal of these algorithms is to recognize the identity, position, and orientation of randomly oriented industrial parts. In one form this is commonly referred to as the "bin-picking" problem, in which the parts to be recognized are presented in a jumbled bin. The paper is organized according to 2-D, 2½-D, and 3-D object representations, which are used as the basis for the recognition algorithms. Three central issues common to each category, namely, feature extraction, modeling, and matching, are examined in detail. An evaluation and comparison of existing industrial part-recognition systems and algorithms is given, providing insights for progress toward future robot vision systems.read more

Shape understanding system: 3D interpretation as a part of the visual concept formation
Zbigniew Les,Magdalena Les +1 more
TL;DR: It is shown that a visual object can be interpreted as a 3D object by assigning it to one of shape classes and the main novelty of the presented method is that the process of interpretation is related to a visual concept represented as a set of symbolic names of the shape classes.

Classification and sampling of shapes through semiparametric Skew-Symmetric Shape Model
Sajjad Baloch,Hamid Krim +1 more
TL;DR: A novel method for shape modeling using an extended class of semiparametric skew-symmetric (SSS) distributions, capable of capturing inherent variability of shapes provided the realization contours remain within a certain neighborhood range around a “mean” with high probability.

Model-based partial shape recognition using contour curvature and affine transformation
Frank Y. Shih,Pingchang Yeh +1 more
TL;DR: The authors present a novel technique for recognizing partially obscured and overlapping objects by using the contour curvature and affine transformation to match the given contour curve against all model objects and select the best matching.

Generalizing the hough transform to detect arbitrary shapes
TL;DR: It is shown how the boundaries of an arbitrary non-analytic shape can be used to construct a mapping between image space and Hough transform space, which makes the generalized Houghtransform a kind of universal transform which can beused to find arbitrarily complex shapes.

Fourier Descriptors for Plane Closed Curves
Charles T. Zahn,Ralph Roskies +1 more
TL;DR: It is established that the Fourier series expansion is optimal and unique with respect to obtaining coefficients insensitive to starting point and the amplitudes are pure form invariants as well as are certain simple functions of phase angles.
