Rotation Calibration of Rigid Spherical Microphone Arrays for Multi-perspective 6DoF Audio Recordings
Olgun, Orhun; Erdem, Ege; Hacıhabiboğlu, Hüseyin (2021-09-08)
The preferred approach for multi-perspective six-degrees-of-freedom (6DoF) audio involves using multiple rigid spherical microphone arrays (RSMA) that can capture higher-order Ambisonics. RSMAs are spherically symmetric an...
Runs of homozygosity suggest a reduction in inbreeding through the Holocene
Gürün, Kanat; Altınışık, Nefize Ezgi; Gemici, Hasan Can; Karamurat, Cansu; Koptekin, Dilek; Vural, Kıvılcım Başak; Mapelli, Igor; Sağlıcan, Ekin; Sürer, Elif; Erdal, Yılmaz Selim; Götherström, Anders; Özer, Füsun; Atakuman, Çiğdem; Somel, Mehmet (2021-06-01)
How the advent of agriculture and social complexity changed human inbreeding patterns is unclear. Ethnographic work suggests low levels of consanguinity in modern-day foragers compared to farmer communities. Meanwhile, t...

Recent studies showed that Neolithic populations in southwest Asia included distinct gene pools in the Levant, in Central Anatolia, and in the Zagros. Further, genomic comparisons suggested that all three populations adopt...
Polyp Detection in Colonoscopy Images using Deep Learning and Bootstrap Aggregation
Polat, Görkem; Işık Polat, Ece; Kayabay, Kerem; Temizel, Alptekin (2021-4-13)
Computer-aided polyp detection is playing an increasingly more important role in the colonoscopy procedure. Although many methods have been proposed to tackle the polyp detection problem, their out-of-distribution test res...
Generative Data Augmentation for Vehicle Detection in Aerial Images
Kumdakçı, Hilmi; Öngün, Cihan; Temizel, Alptekin (null; 2021-01-15)
Scarcity of training data is one of the prominent problemsfor deep networks which require large amounts data. Data augmentationis a widely used method to increase the number of training samples andtheir variations. In this...
