Deep learning based prediction of path loss values and distributions from satellite images
Marey, Ahmed Mohamed Nagib İbrahim (İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2021)It is critical to provide rapid deployment of robust and effective outdoor communication systems in today's world, where many seek to provide wireless connection services from aerial grids of drones and balloons, or low ... -
Dynamic range enhancement in light field imaging systems
Wahab, Abdul (İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2019)High dynamic range imaging has been an active research area in computational photography over the last two decades. The main reason is that the dynamic range of a traditional camera is typically less than the dynamic range ... -
Extending light field camera capabilities
Mukati, Muhammad Umair (İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2017)A traditional camera captures an image by projecting a scene on a two-dimensional image sensor plane regardless of the direction light rays coming onto the sensor. A light field camera, in contrast, records light rays in ... -
Extracting sub-exposure images from a single capture through fourier-based optical modulation
Khan, Shah Rez (İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2017)Through pixel-wise optical coding of images during exposure time, it is possible to extract sub-exposure images from a single capture. Such a capability can be used for different purposes, including high-speed imaging, ... -
Image enhancement through new techniques in computational photography
Alam, Muhammad Zeshan (İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2019)Quality of a digital image depends on several factors operative during the image formation process, e.g. sensor defects, sensor dynamic range, poor spatial resolution,lens distortion, camera shake and object motion. This ... -
Path loss prediction from heightmap using deep learning
Bal, Mustafa (İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2021)Wireless channel parameters of a region are required for a successful network planning. Sufficient information about those parameters can be obtained by either actual measurements or ray-tracing simulations that use 3D ... -
Super resolution of light fields using convolutional neural network
Gul, Muhammad Shahzeb Khan (İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2018)Light field imaging extends the traditional photography by capturing both spatial and angular distribution of light, which enables new capabilities, including post-capture refocusing, post-capture aperture control, and ...
