We introduce a novel algorithm for obtaining High Dynamic Range (HDR) videos from Standard Dynamic Range (SDR) videos with varying shutter speed or ISO per frame. This capturing technique represents today one of the most popular HDR video acquisition methods, thanks to the availability and the low cost of the equipment required; i.e., an off-the-shelf DSLR camera. However, naïvely merging SDR frames into an HDR video can produce artifacts such as ghosts (when the scene is dynamic), and blurry edges (when the camera moves). In this work, we present a straightforward, easy to implement, and fast technique that produces reasonable results in a short time. This is key for having quick previews of the captured videos without waiting for a long processing time. This is extremely important, especially when capturing videos on modern mobile devices such as smartphones and/or tablets.

Directional coding of backward compatible high dynamic range (HDR) image coding residues Feyiz, Kutan; Kamışlı, Fatih; Department of Electrical and Electronics Engineering (2018) High dynamic range (HDR) image and video formats are proposed to overcome limitations of widely accepted standard 8-bit low dynamic range (LDR) image and video representations. The main aim of these formats is to encode the whole luminance range of real world scenes which changes from extreme darkness ( 10 − 6 cd/ m 2 ) to bright sunshine ( 10 8 cd/ m 2 ), and to generate and store such scenes independent from the display technology. To achieve a successful transition from LDR to HDR technology, backward ...
Privacy protection of tone-mapped HDR images using false colours ÇİFTÇİ, Serdar; Akyüz, Ahmet Oğuz; PİNHEİRO, Antonio M. G.; Ebrahimi, Touradj (2017-12-01) High dynamic range (HDR) imaging has been developed for improved visual representation by capturing a wide range of luminance values. Owing to its properties, HDR content might lead to a larger privacy intrusion, requiring new methods for privacy protection. Previously, false colours were proved to be effective for assuring privacy protection for low dynamic range (LDR) images. In this work, the reliability of false colours when used for privacy protection of HDR images represented by tone-mapping operators...
Performance improvement of a 3d reconstruction algorithm using single camera images Kılıç, Varlık; Platin, Bülent Emre; Department of Mechanical Engineering (2005) In this study, it is aimed to improve a set of image processing techniques used in a previously developed method for reconstructing 3D parameters of a secondary passive target using single camera images. This 3D reconstruction method was developed and implemented on a setup consisting of a digital camera, a computer, and a positioning unit. Some automatic target recognition techniques were also included in the method. The passive secondary target used is a circle with two internal spots. In order to achieve...
False color visualization for hdr images Akyüz, Ahmet Oğuz (null; 2013-04-10) Photographic visualization of high dynamic range (HDR) images on low dynamic range (LDR) displays, known as tone mapping, is a well-known problem. However, no well-defined method exist to visualize HDR images for the purpose of scene analysis and understanding. In this paper, we aim to fill this gap by first outlining a general framework that can be used to visualize HDR images using false (i.e. pseudo) colors based on pixel luminances. We then experiment with several simple false coloring functions that ca...
Real-time FPGA firmware for VGA resolution infrared camera Çevik, Kami; Akın, Tayfun; Department of Electrical and Electronics Engineering (2019) Infrared cameras generally require pre-processing on raw image data in order to improve the output image quality. Raw output of the infrared cameras occupies a narrow part of the available dynamic range. Contrast enhancement is one of the pre-processing operations and used for improving dynamic range of the low contrast images. This thesis proposes an adaptive histogram equalization method for enhancing the contrast of long wavelength infrared camera output with 640×480 resolution and provides a FPGA implem...
