Single-image Bayesian Restoration and Multi-image Super-resolution Restoration for B-mode Ultrasound Using an Accurate System Model Involving Correlated Nature of the Speckle Noise. Cüneyitoğlu, Özkul; Mumcuoğlu, Ünal Erkan; Sancak, İT (2019-11-01) B-mode ultrasound is an essential part of radiological examinations due to its low cost, safety, and portability, but has the drawbacks of the speckle noise and output of most systems is two-dimensional (2D) cross sections...
Biyomedikal Mühendisliği ve Uygulamaları Cüneyitoğlu Özkul, Mine; Mumcuoğlu, Ünal Erkan (TMMOB, EMO Ankara Şubesi, 2019-01-01)
Chapter 13: Acceptance of Mobile Homecare Technologies: An Empirical Investigation on Patients with Chronic Diseases Özkan Yıldırım, Sevgi; Mumcuoğlu, Ünal Erkan (null, 2018-01-01) In this study, the factors affecting the acceptance of mobile homecare system were investigated. The factors were assessed by employing unified theory of acceptance and use of technology (UTAUT) as a theoretical model. The...
A validated active contour method driven by parabolic arc model for detection and segmentation of mitochondria Tasel, Serdar F.; Mumcuoğlu, Ünal Erkan; Hassanpour, Reza Z.; Perkins, Guy (2016-06-01) Recent studies reveal that mitochondria take substantial responsibility in cellular functions that are closely related to aging diseases caused by degeneration of neurons. These studies emphasize that the membrane and cris...
Bayesian segmentation of human facial tissue using 3D MR-CT information fusion, resolution enhancement and partial volume modelling Şener, Emre; Mumcuoğlu, Ünal Erkan; Hamcan, Salih (2016-02-01) Background: Accurate segmentation of human head on medical images is an important process in a wide array of applications such as diagnosis, facial surgery planning, prosthesis design, and forensic identification.
Automatic detection of mitochondria from electron microscope tomography images: a curve fitting approach Tasel, Serdar F.; HASSANPOUR, REZA; Mumcuoğlu, Ünal Erkan; Perkins, Guy; Martone, Maryann (2014-02-18) Mitochondria are sub-cellular components which are mainly responsible for synthesis of adenosine tri-phosphate (ATP) and involved in the regulation of several cellular activities such as apoptosis. The relation between som...
Image Analysis for Cystic Fibrosis: Computer-Assisted Airway Wall and Vessel Measurements from Low-Dose, Limited Scan Lung CT Images Mumcuoğlu, Ünal Erkan; Castile, Robert G.; Gurcan, Metin N. (2013-02-01) Cystic fibrosis (CF) is a life-limiting genetic disease that affects approximately 30,000 Americans. When compared to those of normal children, airways of infants and young children with CF have thicker walls and are more ...
Automatic segmentation of human facial tissue by MRI-CT fusion: A feasibility study Kale, Emre H.; Mumcuoğlu, Ünal Erkan; HAMCAN, Salih (2012-12-01) The aim of this study was to develop automatic image segmentation methods to segment human facial tissue which contains very thin anatomic structures. The segmentation output can be used to construct a more realistic human...
Computerized detection and segmentation of mitochondria on electron microscope images Mumcuoğlu, Ünal Erkan; Tasel, S. F.; Perkins, Guy; Martone, M. E.; Gurcan, M. N. (2012-06-01) Mitochondrial function plays an important role in the regulation of cellular life and death, including disease states. Disturbance in mitochondrial function and distribution can be accompanied by significant morphological ...
Computerized scar detection on renal cortical scintigraphy images Mumcuoğlu, Ünal Erkan; Aslan, Mehmet; Sener, Emre; UĞUR, ÖMER (2011-11-01) Objective Renal cortical scintigraphy is a well-established functional imaging technique for visual analysis of radiopharmaceutical tracer distribution. However, the visual evaluation is subjective, causing interobserver v...
