چکیده

A grid method for measuring the shape and strain distribution of 3D objects by using the Fourier transform grid method is presented. In the conventional automated grid method, the position of a line is expressed in an integer, so it is difficult to analyze the accurate position. Using this twodimensional Fourier transform grid method the fault can be overcome by analyzing and interpolating the phase distribution. Using it, the two dimensional grating can be easily scparated to xand y-grating based on its orthogonality.

Visual Tracking using Kernel Projected Measurement and Log-Polar Transformation

Visual Servoing is generally contained of control and feature tracking. Study of previous methods shows that no attempt has been made to optimize these two parts together. In kernel based visual servoing method, the main objective is to combine and optimize these two parts together and to make an entire control loop. This main target is accomplished by using Lyapanov theory. A Lyapanov candidat...

3D Models Recognition in Fourier Domain Using Compression of the Spherical Mesh up to the Models Surface

Representing 3D models in diverse fields have automatically paved the way of storing, indexing, classifying, and retrieving 3D objects. Classification and retrieval of 3D models demand that the 3D models represent in a way to capture the local and global shape specifications of the object. This requires establishing a 3D descriptor or signature that summarizes the pivotal shape properties of th...

Dynamic 3-D shape measurement method A review

Three-dimensional (3-D) shape measurement for a dynamic object or process, whose height distributions is varying with the time, has been a hot topic in recent years due to its wide field of application. A number of techniques have been presented and in-depth studied. Among several noncontact 3-D shape measurements for a dynamic object or process, an optical 3-D measurement system, based on 2-D ...

Augmenting the Concept of Shape Numbers for 3-d Shape Recognition

Abstract Shape recognition plays a crucial role in image processing. This work proposes a method for object recognition, based on boundary detection by combining the concept of Fourier descriptors, wavelet transform and shape number. The main aim is to identify the shape of the object from the features that are drawn out from the boundary of the object. The boundary of the object of interest is...

An E cient Fourier Method for 3 D RadonInversion in Exact Cone - Beam

| The 3D Radon transform of an object is an important intermediate result in many analytically exact cone-beam reconstruction algorithms. In this paper, we present a new, highly eecient method for 3D Radon inversion, i.e. reconstruction of the image from the 3D Radon transform, called Direct Fourier Inversion (DFI). The method is based directly on the 3D Fourier Slice Theorem. From the 3D Radon...
