    Artificial 3-D contactless measurement in orthognathic surgery with binocular stereo vision
    (ELSEVIER SCIENCE BV, 2016) Comlekciler, Ismail Taha; Gunes, Salih; Irgin, Celal
    Stereo vision systems are utilized since it provides contactless measurements of objects in 3-D (threedimensional). Orthognathic surgery is a very sensitive operation that requires very high accuracy in measurements. The reduction of measurement error is an essential problem in orthognathic surgery. Moreover, quality inspection of the process during the course of operation aids the surgeon to avoid or minimize the mitigating circumstances. In this paper, artificial intelligence methods (neural network and neuro-fuzzy system) are used in order to increase the accuracy of positioning of jaws during the real-time practice. The comparison of artificial measurements with the real measurements shows that a statistically acceptable accuracy is achieved in 3-D positioning of teeth. (C) 2016 Elsevier B.V.

    Measuring The Optimum Lux Value for More Accurate Measurement of Stereo Vision Systems in Operating Room of Orthognathic Surgery
    (IEEE, 2014) Comlekciler, Ismail Taha; Gunes, Salih; Irgin, Celal; Karlik, Bekir
    The successful orthognathic surgery is directly influenced by more accurate measurement of distance or size of the surgery area. There exist various methods of measurements during the orthognathic surgery. One of the newest methods is to make measurements by using stereo vision system with stereo cameras. The result of stereo vision is affected by many factors, such as captured image colour, glossiness, ambient light, geometry, etc. One of the most important influence factors is ambient light, especially on measuring distances with the value of microns (10-6 m). The stereo vision system's cameras are also influenced by ambient light and the objective of this paper is to investigate more accurate result of stereo vision according to the ambient light of the orthognathic surgery operation room.
