Sampling on Concentric Circles
— Two forms of a sampling theorem for concentric circles are established for a bandlimited two-dimensional (2-D) function. The location of the samples is prescribed either on equ...

Planar Curve Representation and Matching
In this paper, we discuss a method for representing and matching planar curves. The technique is based on using calculations from concentric circles to represent each curve by two...

Rendering with Concentric Mosaics
This paper presents a novel 3D plenoptic function, which we call concentric mosaics. We constrain camera motion to planar concentric circles, and create concentric mosaics using a...

Computing Radial Drawings on the Minimum Number of Circles
A radial drawing is a representation of a graph in which the vertices lie on concentric circles of finite radius. In this paper we study the problem of computing radial drawings ...

An Algorithm for the Detection of Multiple Concentric Circles
This paper presents a method for the detection of multiple concentric circles which is based on the Hough Transform (HT). In order to reduce time and memory space the concentric ci...

Virtual Reality Using the Concentric Mosaic: Construction, Rendering and Data Compression
This paper proposes a new image based rendering technique called concentric mosaic for virtual reality applications. It is constructed by capturing vertical slit images when a cam...

Detection of Concentric Circles for Camera Calibration
The geometry of plane-based calibration methods is well understood, but some user interaction is often needed in practice for feature detection. This paper presents a fully automa...
