Effect of distance metrics on positioning accuracy [Uzaklik metriklerinin konumlama başarimina etkisi]
Altın, U. C.; At, Nuray; Topal, C. (Institute of Electrical and Electronics Engineers Inc., 2018)RF fingerprinting based positioning systems have come to the forefront among indoor positioning systems as they provide both high precision and can use existing infrastructure like Wi-Fi access points effectively. In this ... -
Effectiveness of online RF fingerprinting for indoor localization
Othman, H.; At, Nuray; Topal, C. (Institute of Electrical and Electronics Engineers Inc., 2018)This paper proposes a method for indoor localization by introducing an online Radio Frequency (RF) fingerprinting approach instead of the traditional offline RF fingerprinting. The offline phase is a time-consuming stage ... -
Expression recognition with appearance-based features of facial landmarks [Yuz nirengi noktalarinin görünüş öznitelikleri ile ifade tanima]
The human face is the subject of many studies in the field of artificial vision because of the high amount of semantic information. The most common of the studies carried out in this area are face analysis and expression. ... -
Gender recognition with uniform local binary patterns [Tekduze yerel ikili örüntuler ile cinsiyet tanima]
Cerkezi, L.; Topal, C. (Institute of Electrical and Electronics Engineers Inc., 2018)Automatic gender recognition has been applied in many areas such as analyzing the structure of demographic social environments. In this paper we present a gender recognition algorithm based on uniform local binary pattern ... -
Logo recognition via fusion of spatial and spectral features [Uzamsal ve spektral öznitelik birleşimi ile logo tanima]
Shakir, S.; Gacav, Caner; Topal, C. (Institute of Electrical and Electronics Engineers Inc., 2018)Machine vision based logo and trademark recognition, is one of the most efficient and widely used method to measure brand awareness on internet and social media.

Patch warping based face frontalization [Yama çarpitma tabanli yüz önleştirme]
Erdem, M. E.; Topal, C. (Institute of Electrical and Electronics Engineers Inc., 2018)Face frontalization increases accuracies of face and gesture recognition applications. In this paper, we propose a 2D patch warping based face frontalization method which that has a simple but efficient flow due to its ... -
Sequential forward feature selection for facial expression recognition [Yüz Ifadesi Tanima Için Ardisik Ileri Öznitelik Seçimi]
Gacav, Caner; Benligiray, Burak; Topal, C. (Institute of Electrical and Electronics Engineers Inc., 2016)Facial expression recognition is an important computer vision problem with various applications. In this study, we investigate the effectiveness of features derived from facial landmarks in facial expression recognition. ...
