In several image processing applications one has to deal with noisy images defined on surfaces, like electric impulsions or diffusion tensors on the cortex. We propose a new regularization technique for data defined on triangulated surfaces: the Beltrami flow over intrinsic manifolds. This technique overcomes the over smoothing of the L2 and the stair-casing effects of the L1 flow for strongly ...

China Abstract In this paper, we introduce the binomial sequence spaces b 0 (B (m)), ba,b c (B (m)) and ba,b ∞ (B(m)) by combining the binomial transformation and difference operator. We prove the BK-property and some inclusion relations. Furthermore, we obtain Schauder bases...

This paper proposes an algorithm that can improve performance by searching for tone mapping optimized for three types of images through image analysis while maintaining a tone mapping shape based on human visual characteristics. The algorithm uses the optimized Retinex-based color restoration technique by analyzing three types of images based on luminance: highand low-luminance images and image...

INTRODUCTION There is still no consensus in the literature as to the best acoustic stimulus for capturing vestibular evoked myogenic potential (VEMP). Low-frequency tone bursts are generally more effective than high-frequency, but recent studies still use clicks. Reproducibility is an important analytical parameter to observe the reliability of responses. OBJECTIVE To determine the reproducib...

[Purpose] This study was conducted to compare and analyze influence of craniocervical flexion and suboccipitalis relaxation in cervicogenic headache patients of their cervical muscular fatigue, tone, and headache intensity. [Subjects and Methods] 30 patients with cervicogenic headache were selected and 10 subjects per group were randomly assigned to control group, craniocervical flexion exercis...

OBJECTIVE To determine the hearing levels of participants of a randomized group using a smartphone hearing application and to compare these results with the results from a pure-tone audiogram. MATERIALS AND METHODS A heterogenous group consisting of both normal-hearing and hearing-impaired participants were included in this study. Pure-tone audiogram thresholds were measured from 250 Hz to 80...

The pathophysiology of aortic dissection is poorly understood, and its risk is resistant to medical treatment. Most studies have focused on a proposed pathogenic role of transforming growth factor-β in Marfan disease and related thoracic aortic aneurysms and aortic dissections. However, clinical testing of this concept using angiotensin II type 1 receptor antagonists to block transforming growt...

Lexical tone perception in Thai adults with normal hearing and those with sensorineural hearing-loss using hearing aids was investigated to evaluate the benefit of using hearing aids for tone perception. Tone perception pattern across groups was also compared. Identification tests (with white noise and clean conditions) using a two alternative forced choice task were carried out to systematical...

Few studies focused on the tonal realization of first syllables in disyllabic words with tonal combination of “canonical tone + neutral tone” in Mandarin. To fill in the void, the present study compared the prosodic characteristics of first syllables between minimal pairs of neutral tone word (NW) and canonical tone word (CW). The results show that (1) For duration, no difference was found. (2)...
