Based on first-principles calculations and effective model analysis, all possible straight nodal-line phonons in symmorphic space groups are uncovered. A classification of two-band ${\textbf{k}}\cdot {\textbf{p}}$ models at an arbitrary point the nodal lines is carried out, these found to locate along high symmetry Brillouin zone. According our classification, there two types groups. The first ...

When the Hough transform is applied to the detection of straight lines in images, it provides only the parameters of the line but not the length or the end points of the line. We propose a new algorithm for the determination of the length and the end points of a line in an image. It is very eecient in terms of computing time and does not depend on the sharpness of the peak in the accumulator ar...

The Hough Transform (HT) is a method for extracting straight lines from an edge image. The main limitations of the HT for usage in actual applications are computation time and storage requirements. This paper reports a hardware architecture for HT implementation on a Field Programmable Gate Array (FPGA) with parallelized voting procedure. The 2-dimensional accumulator array, namely the Hough sp...

The Psi-s plot represents the geometry of a line by determining Psi, the orientation angle or heading, at points along the line, and plotting that value against s, the cumulative curvilinear distance along the line. No matter how convoluted the line is, the Psi-s plot will be a single-valued function of s; it is much easier to parameterize such a single-valued function. Straight lines on the Ps...

In this paper, we propose a new method to adapt the resolution of images to the limited display resolution of mobile devices. We use the seam carving technique to identify and remove less relevant content in images. Seam carving achieves a high adaptation quality for landscape images and distortions caused by the removal of seams are very low compared to other techniques like scaling or croppin...
