Between Crises and Fragile Stability: Turkiye-Israel Affairs
(Turkish Policy Quarterly, 2022) Adisonmez, Umut Can; Oztig, Lacin Idil
Since the establishment of Israel, the Turkish-Israeli relations have been marked by continuous periods of swings - from crises to cooperation and back. This article aims to shed light on the turbulent bilateral ties by focusing on the role of the current Justice and Development Party (JDP) rule in Turkiye. In doing so, it firstly provides a background on the two countries' relations, covering the period between their foundational years and 2002. Secondly, it explores a series of significant crises against which the Turkish-Israeli relations reached an all-time low starting with the Operation Cast Lead in 2008. Given the recent developments unfolding in Turkiye's domestic sphere and its close geography, this work lastly assesses the impact of the Abraham Accords in 2020 on bilateral relations and speculates about the future trajectories.

Quest for Regional Hegemony: the Politics of Ontological Insecurity in the Saudi-Iran Rivalry
(Sage Publications Inc, 2022) Adisonmez, Umut Can; Onursal, Recep; Oztig, Lacin Idil
The rivalry between Iran and Saudi Arabia has been unfolding over a long period, influencing the politics and conflicts in the Middle East. The dynamics, content, and form of the rivalry have changed dramatically following the Iranian Revolution in 1979. Sectarianism is frequently seen as the constitutive element of the conflict between the two countries. This paper brings a new light into the literature on the nature of the evolving Saudi-Iran rivalry. Specifically, it explains Saudi Arabia's ideational balancing and threat perception against Iran by highlighting the ontological security narratives under which the Saudi-Iran rivalry evolves. In doing so, it draws on the fatwas (i.e., religious opinions), issued by Saudi scholars, as an empirical object of investigation, and explores how they constitute and reconstitute Saudi Arabia's ontological security narratives. In this way, this work critically explains the ontological security regime in Saudi Arabia and the nature of the political struggle and antagonism between the two countries.

Underwater Image Dehazing via Red-Channel Recovery
(European Signal Processing Conference, EUSIPCO, 2023) Petenkaya, E.D.; Oztig, Lacin Idil; Türkan, Mehmet; Kara, O.F.
Due to light scattering and absorption while traveling through water, underwater images become hazy and loose critical information resulting in poor contrast and weak color performance. Hence, it is difficult to see the difference between foreground colors and items, and to differentiate the background in these images. To solve these issues, this study proposes a novel technique for single underwater image enhancement which relies on the recovery of the lost red-channel via a weighted multi-scale fusion. Firstly, three color balance algorithms are applied to the input image to gain more information about the scene. Then, five weight maps are extracted from these balanced versions of the input image to emphasize fine-details. Finally, the enhanced output is obtained with the new red-channel, white balanced green and blue channels followed by gamma correction to maintain contrast of the image. The developed method produces higher-quality underwater images that can be evaluated qualitatively and quantitatively when compared to state-of-the-art approaches. © 2023 European Signal Processing Conference, EUSIPCO.
