Yarn hairiness is one of the key parameters influencing fabric quality. In this paper image processing and analysis algorithms developed for an automatic determination of yarn hairiness are presented. The main steps of the proposed algorithms are as follows: image preprocessing, yarn core extraction using graph cut method, yarn segmentation using high pass(More)
BACKGROUND The aim of this study was to evaluate distortion product otoacoustic emissions (DPOAEs) and extended high-frequency (EHF) thresholds in a control group and in patients with normal hearing sensitivity in the conventional frequency range and reporting unilateral tinnitus. MATERIAL/METHODS Seventy patients were enrolled in the study: 47 patients(More)
The patients with tinnitus and/or hyperacusis undergoing an 18-24 month period of TRT are divided into five categories of treatment. Different types of counselling and sound therapy are used in each category. Selection of patients into a specific category depends on such factors as: hyperacusis, subjective hearing loss and long-lasting effect of noise on(More)
Introduction. Although tinnitus often has a significant impact on individual's life, there are still few reports relating to tinnitus in children. In our tinnitus clinic, children with distressing tinnitus constitute about 0,5% of all our patients. Objectives. The aim of this study was to analyse children with troublesome tinnitus as regards epidemiology,(More)

—This paper describes a framework for establishing a reference airway tree segmentation, which was used to quantitatively evaluate 15 different airway tree extraction algorithms in a standardized manner. Because of the sheer difficulty involved in manually constructing a complete reference standard from scratch, we propose to construct the reference using(More)
AIM OF THE STUDY To evaluate the influence of high frequency hearing loss (> 8000 Hz) on distortion product otoacoustic emissions registered in the frequency range from 0,5 to 8 kHz. MATERIAL AND METHODS 280 ears with tinnitus and normal hearing (0.25-8 kHz) divided into 3 groups depending on the degree of high frequency hearing loss: group A--hearing(More)
Distortion Product Otoacoustic Emission (DPOAE) has been used as a tool to determine the presence of cochlear pathology. It is well known that the damage of Outer Hair Cells (OHCs) results in reduced auditory sensitivity and generation of tinnitus. At the same time tinnitus arises in normal hearing persons as well. The aim of this study was the assessment(More)
