The shear deformation \(\varepsilon _{xy}\) and the rotation \(\omega _{xy}\) show loops oriented along the horizontal direction, parallel to the Burgers vector. Visually, the shape of the experimental and theoretical deformation fields is in good agreement. In order to provide a ...
\(\mathbf {LSM}\):Images are divided in little patches and in each one of them two feature vector are obtained. The first vector is associated to each full-quaternion in the patch and their elements are the module and phase (see Eqs. (2) and (3)). The second feature vector has the...
The rest of the paper is structured as follows. First, in “Related work” we briefly describe previous techniques focused on the reduction of the mixture of Gaussian and impulsive noise. Afterwards, in “Mean shift and its fast modifications” the Mean Shift technique is presented and we provi...
The external orientation of images include the spatial (X, Y, Z) and angular (omega, phi y kappa) positions. Finally, these positions are refined by a bundle adjustment complemented with the collinearity condition based on the Gauss–Newton method [39], obtaining the final external orientation ...
