Grey Wolf Optimizer (GWO) is one of the recently introduced Swarm Intelligence (SI) algorithms, developed by the inspiration from grey wolves prey search characteristics. The GWO algorithm imitate the hierarchical leadership and hunting mechanism of grey wolves in nature. The GWO simulates the major steps of grey wolves like hunting, searching for prey, encircling and attacking. The GWO move the wolves...
We present a novel method for computing depth of field and geometry from a single 2D image. This technique, unlike the existing ones measures the absolute depth of field and distances in the scene from single image only using the concept of triangulation. This algorithm requires minimum inputs such as camera height, camera pitch angle and camera field of view for computing the depth of field and 3D...
Real world contains a wide range of intensities that cannot be captured with traditional imaging devices. Moreover, even if these images are captured with special procedures, existing display devices cannot display them. This paper presents a comparative study of most famous tone mapping algorithms. Tone mapping is the process of compressing high dynamic range images into a low dynamic range so they...
Filter-based fading channel simulators universally use White Gaussian Noise (WGN) to generate complex tap coefficients. In this work, we will show that replacing WGN source by Uniform Random Number Generator (URNG) results in improved simulation speed in case of software simulator; and reduced area/power in case of hardware simulator. We will verify, both analytically and through extensive simulations,...
Interpolation filters are considered to be computationally intensive sections of fading channel simulators. They can be implemented by using linear interpolation or zero-padding followed by low-pass IIR or polyphase filtering. In this work, we will investigate how different interpolation techniques affect statistical properties and speed of the simulator. We will show that use of linear interpolation...
Presented is a new computational method for predicting the static cross-sectional thickness profile of rolled metal strip. Methods to model the strip profile and related flatness with improved efficiency and accuracy remain central for achieving high quality flat-rolled products. The new method involves a novel combination of Timoshenko beam finite elements with multiple coupled Winkler elastic foundations...
