Visual Regression is a general task in the area of computer vision, with input visual data space and continuous output space. Most learning-based visual estimation tasks, where the output variables take values in continuous space, are related to visual regression. Examples of visual regression include many emerging but very difficult...
In the last decade, global mobile data traffic increased by more than a hundred fold times while maintaining essentially the same monthly charge to the average mobile user. Cisco predicts that overall mobile data traffic will continue to grow rapidly at a compound annual growth rate of 60 percent between...
2018-1The human visual system has a remarkable ability for understanding material properties on the basis of texture appearance, such as', 'telling whether the food is fresh, the fabric is soft, the soil is wet, or the skin is dry. Such visual judgments of material properties mostly rely on the perception...
Ultrathin optical platform including two-dimensional materials and metasurfaces have emerged as potential candidates for novel nanophotonic applications. In this dissertation, I will present the possibility to achieve full active control of the electromagnetic waves with the platform in the flatland. We could achieve the amplitude control, which will be useful...
Maxwell equations are behind an incredible number of physical phenomena, explaining the behavior of light, electricity and magnetism, from Gamma rays to ultra-low frequency radio-waves. Since their inception in 1861, many approximations have been derived, many devices have been modelled and fabricated to manipulate the electromagnetic fields, and more recently...
In this dissertation thesis, I introduce three-dimensional (3D) image reconstruction algorithms for multi-focus microscopy (MFM). MFM provides a fast way to obtain 3D information of the sample by simultaneously capturing multiple focal planes on a single camera shot. However, stacking the sub-images from different focal planes does not provide a...
Neural networks have revolutionized the field of computer vision since they provide solutions to a number of previously unsolved problems and achieve promising performance both in terms of accuracy and computational efficiency. It has increasingly become recognized as providing high performance for applications as diverse as image classification, object detection,...
Free space optical communication (FSO) offers a promising solution to the “last mile” bottleneck of high-speed telecommunications. Data is encoded using a modulated laser and optically sent through the air to a receiving photodetector. Although this requires FSO systems to have direct line-of-sight between the emitter and receiver, this is...
This project is comprised of primary source research on the field of semiconductor microscopy. We were interested in determining a more interdisciplinary application of this technology, as the most frequently cited applications are for defense purposes such as drug screening or infrared imaging. When we researched, we found that these...
Agents of online platforms often have to make purchase decisions in the face the uncertainty of the true value of an item. Observing the other agents’ actions and/or reviews is one common method to learn about an item. However such observational learning can lead to an information cascade, in which...
