A Compact Multi-Exposure File Format for Backward and Forward Compatible HDR Imaging Sekmen, Selin; Akyüz, Ahmet Oğuz (2024-01-01) High dynamic range (HDR) imaging techniques offer photographers the ability to capture the full range of luminance in real-world scenes, overcoming the limitations of capture and display devices. One popular method for cre...
Denoising and Guided Upsampling of Monte Carlo Path Traced Low Resolution Renderings Alpay, Kadir Cenk; Akyüz, Ahmet Oğuz (2022-07-27) Monte Carlo path tracing generates renderings by estimating the rendering equation using the Monte Carlo method. Studies focus on rendering a noisy image at the original resolution with a low sample per pixel count to decr...
An Approach to Analyzing the Layout of Unstructured Digital Documents Atay, Mert; Kalaycı, Meltem; Apik, Hasan; Aybar, Vedat; SERİN, FARUK; Akyüz, Ahmet Oğuz (2022-05-15)
Object Detection for Autonomous Driving: High-Dynamic Range vs. Low-Dynamic Range Images Kocdemir, Ismail H.; Akyüz, Ahmet Oğuz; Koz, Alper; Chalmers, Alan; Alatan, Abdullah Aydın; Kalkan, Sinan (2022-01-01) An important problem in autonomous driving is to perceive objects even under challenging illumination conditions. Despite this problem, existing solutions use low-dynamic range (LDR) images for object detection for autonom...
HDR IMAGE CONSTRUCTION FROM TRIFOCAL MULTIEXPOSURE IMAGES KOZ, ALPER; Demirkılıç, Barış; Kurt, Yunus Bilge; Akyüz, Ahmet Oğuz; Kalkan, Sinan; Alatan, Abdullah Aydın; Chalmers, Alan (2021-10-06) With the progress of autonomous vehicles, the sensing of the environment in more detail with higher dynamic ranges has become more important to classify surrounding objects and obstacles. While stereo HDR images for this p...
From Noon to Sunset: Interactive Rendering, Relighting, and Recolouring of Landscape Photographs by Modifying Solar Position Ture, Murat; Ciklabakkal, Mustafa Ege; Erdem, Aykut; Erdem, Erkut; SATILMIŞ, PINAR; Akyüz, Ahmet Oğuz (2021-08-01) Image editing is a commonly studied problem in computer graphics. Despite the presence of many advanced editing tools, there is no satisfactory solution to controllably update the position of the sun using a single image. ...
An experimental evaluation of visual similarity for HDR images Aydinlilar, Merve; Akyüz, Ahmet Oğuz; Tarı, Zehra Sibel (2021-07-01) In this paper, we investigate visual similarity for high dynamic range (HDR) images. We collect crowdsourcing data through a web-based experimental interface, in which the participants are asked to choose one of the two ca...
Realistic Lighting for Interactive Applications Using Semi-Dynamic Light Maps Öztürk, Bekir; Akyüz, Ahmet Oğuz (2020-12-01) Light mapping is a technique that works by precomputing the lighting of a scene to speed up expensive lighting calculations at run-time. It is a commonly employed technique for computer games, in particular mobile games, d...
Just Noticeable Quantization Levels For High Dynamic Range Images Sozer, Sevim Begum; Koz, Alper; Akyüz, Ahmet Oğuz; Zerman, Emin; Valenzise, Giuseppe; Dufaux, Frederic (2020-10-25) Just noticeable quantization levels, which are conventionally used in picture coding, have been mainly developed for standard 8-bit images and low dynamic range (LDR) typical screens. The quantization levels however have n...
An Experimental Method to Determine Quantization Levels for High Luminance Patterns Sözer, Sevim Begüm; Koz, Alper; Akyüz, Ahmet Oğuz; Zerman, Emin; Valenzise, Giuseppe; Dufaux, Frederic (2020-10-05) The quantization levels, which forms an important basis for video coding, are mainly determined for 8-bit image representation and for low dynamic range (LDR) typical displays with a luminance level of 100-500 cd/ m 2 .
