Capıllary Refıll Tıme Measurement Devıce
Bal, Ufuk (2018)Capillary refill time (CRT) can be defined as a rapid clinical test for assessing blood flow through peripheral tissues. Importance of the monitarisation of the CRT is emphasized in diagnosis and treatment guideleness for ... -
Dual tree complex wavelet transform based denoising of optical microscopy images
Bal, Ufuk (Optical Soc Amer, 2012)Photon shot noise is the main noise source of optical microscopy images and can be modeled by a Poisson process. Several discrete wavelet transform based methods have been proposed in the literature for denoising images ... -
A multiresolution approach for enhancement and denoising of microscopy images
Bal, Ufuk; Engin, Mehmet; Utzinger, Urs (Springer London Ltd, 2015)In order to overcome blurring due to microscope optics in fluorescence microscopy, we propose a wavelet transform-based non-iterative blind deconvolution method. In our proposed deconvolution algorithm, we used wavelet-based ... -
Non-contact estimation of heart rate and oxygen saturation using ambient light
Bal, Ufuk (Optical Soc Amer, 2015)We propose a robust method for automated computation of heart rate (HR) from digital color video recordings of the human face. In order to extract photoplethysmographic signals, two orthogonal vectors of RGB color space ... -
Noninvasive Hemoglobin Measurement Reduce Invasive Procedures in Thalassemia Patients
Bıcılıoğlu, Yüksel; Bal, Alkan; Demir Yenigürbüz, Fatma; Ergönül, Esin; Geter, Süleyman; Kazanamaz, Halil; Bal, Ufuk (TAYLOR & FRANCIS LTD, 2022)This study was conducted to investigate the agreement between laboratory hemoglobin (LabHb) measured in venous blood and noninvasive, spectrophotometric hemoglobin (SpHb) measurement and the usability of SpHb measurement ... -
Temassız Fotopletismografi ile Nabız Kestiriminde Hemoglobin Seviyesinin Etkisi
Bal, Ufuk; Bal, Alkan (2015)Temassız fotopletismografinin oksimetrelere daha ucuz bir alternatif olarak kullanılabilmesi için olası hata kaynaklarının araştırılması önemlidir. Temassız nabız tahmini yapan çalışmaların pek çoğu sağlıklı gönüllüler ...
