Analysis of the Superposition of Periodic Layers and TheirMoiré Effects through the Algebraic Structure of Their FourierSpectrum
A new approach is presented for investigating the superposition of any number of periodic structures, and the moiré effects which may result. This approach, which is based on an algebraic analysis of the Fourier-spectrum using concepts from the theory of ...
Preserving Topology by a Digitization Process
The main task of digital image processing is to recognize properties of real objects based on their digital images. These images are obtained by some sampling device, like a CCD camera, and represented as finite sets of points that are assigned some ...
Differentiation-Based Edge DetectionUsing the Logarithmic Image Processing Model
The logarithmic image processing (LIP) model is a mathematical framework which provides a specific set of algebraic and functional operations for the processing and analysis of intensity images valued in a bounded range. The LIP model has been proved to ...
Robust Estimation of Rotation Angles from Image Sequences Usingthe Annealing M-Estimator
A robust method is presented for computing rotation angles of image sequences from a set of corresponding points containing outliers. Assuming known rotation axis, a least-squares (LS) solution are derived to compute the rotation angle from a clean data ...
