Gems - Geometric Median Shapes

2019 IEEE 16th International Symposium on Biomedical Imaging (ISBI 2019), 2019
We present an algorithm to compute the geometric median of shapes which is based on the extension of median to high dimensions. The median finding problem is formulated as an optimization over distances and it is solved directly using the watershed method as an optimizer.

Geometrically Shaped 16QAM Outperforming Probabilistically Shaped 16QaM

2017 European Conference on Optical Communication (ECOC), 2017
We compare the proposed geometrically-shaped(GS) 16QAM with the probabilistically-shaped(PS) 16QAM formats in both numerical simulation and experimental setup. The results show that GS-16QAM outperforms PS-16QAM.

Geometric Sensing of Known Planar Shapes

The International Journal of Robotics Research, 1996
Industrial assembly involves sensing the pose (orientation and position) of a part. Efficient and reliable sensing strategies can be developed for an assembly task if the shape of the part is known in advance. In this article we investigate two problems of determining the pose of a polygonal part of known shape for the cases of a continuum and a finite

A Geometric Framework for Rectangular Shape Detection

IEEE Transactions on Image Processing, 2014
Rectangular shape detection has a wide range of applications, such as license plate detection, vehicle detection and building detection. In this paper, we propose a geometric framework for rectangular shape detection based on the channelscale space of RGB images.

Geometric Shapes of Nuclei

2015
In this chapter we shall study nuclear sizes and shapes by means of elastic electron-nucleus scattering. Electron scattering is particularly valuable for investigating small objects. The electromagnetic interaction between an electron and a nucleus may be very accurately calculated.

Discrete geometric shapes

1996
In this survey we consider geometric techniques which have been used to measure the similarity or distance between shapes, as well as to approximate shapes, or interpolate between shapes. Shape is a modality which plays a key role in many disciplines, ranging from computer vision to molecular biology.

Guessing Geometric Shapes

The Mathematics Teacher, 1987
Searching for commonalities and recognizing distinguishing characteristics are important problem-solving strategies. During the study of geometry, students are bombarded with the properties of numerous geometric figures and can benefit from opportunities to integrate all these ideas.

Geometric Analysis of Continuous, Planar Shapes

2003
We propose two differential geometric representations of planar shapes using: (i) direction functions and (ii) curvature functions, of their boundaries. Under either representation, planar shapes are treated as elements of infinite-dimensional shape spaces. Pairwise differences between the shapes are quantified using the lengths of geodesics connecting
