Abstract Networks can describe the structure of a wide variety complex systems by specifying which pairs entities in system are connected. While such pairwise representations flexible, they not necessarily appropriate when fundamental interactions involve more than two at same time. Pairwise nonetheless remain ubiquitous, because higher-order often recorded explicitly network data. Here, we int...
This paper addresses the post-war reconstruction experience of Qasr-e-Shirin, Iran, in the aftermath of the Iran-Iraq war (1980-1988). Compared with the war-damaged cities in southwest Iran, western cities such as Qasr-e-Shirin lack a post-war reconstruction assessment and documentation. With an objective view, the author aims at documenting the situation of the city almost thirty years after i...
The purpose of this study was to the comparison of the effectiveness of semantic cognitive reconstruction therapy and self-encouragement therapy on chronic fatigue in people with psychosomatic skin. The research method was quasi-experimental with a pretest-posttest design with the control group. The statistical population of the study included people with psychosomatic skin who were referred to...
In this work, a new affine invariant of parallelograms is introduced, and the explicit constraint equations between the intrinsic matrix of a camera and the similar invariants of a parallelogram or a parallelepiped are established using this affine invariant. Camera calibration and 3D reconstruction from parallelograms are systematically studied based on these constraints. The proposed theoreti...
This paper describes a new audio coding scheme based on sinusoidal coding of signals. Sinusoidal coding permits the representation of a given signal through the summation of sinusoids. The parameters of the sinusoids (the amplitudes, phases and frequencies) are transmitted to allow the signal reconstruction. In the proposed scheme, the sinusoidal parameters are sorted according to energy conten...
In this work, we proposes a simple yet effective method for improving performance of local feature matching among equirectangular cylindrical images, which brings more stable and complete 3D reconstruction by incremental SfM. The key idea is to exiplictly generate synthesized images by rotating the spherical panoramic images and to detect and describe features only from the less distroted area ...
In this paper we consider the problem of reconstructing a highresolution image from an incomplete set of undersampled. shifted, degraded frames with subpixel displacement errors. We derive mathematical expressions for the calculation of the maximum a posteriori (MAP) estimate of the high resolution image given the low resolution observed images. We also examine the role played by the prior mode...
We demonstrate a generic method for visualization of high-resolution unorganized and noisy 3D data points with a surface of significantly lower resolution. To this effect, we feed our algorithm with all the go Light Detection And Ranging (LiDAR) data and approximate it with a triangular mesh that is being deformed iteratively until convergence. Our main contribution is avoiding the direct trian...
