OBJECTIVES To develop and validate strategies, using new ultrasound-based mathematical models, for the prediction of high-risk endometrial cancer and compare them with strategies using previously developed models or the use of preoperative grading only. METHODS Women with endometrial cancer were prospectively examined using two-dimensional (2D) and three-dimensional (3D) gray-scale and color ...

This paper presents the comparisons of the latest subjective video sequence quality assessment methods versus objective quality assessment using H.261, H.263+ and H.264 advanced video coding (AVC). A Simultaneous Double Stimulus for Continuous Evaluation (SDSCE) method was used for subjective quality assessment. The Peak Signal to Noise Ratio (PSNR) method and the-state-of-the art Structural SI...

This chapter provides an overview of the various methods and techniques used for assessment of speech quality. A summary is given of some of the most commonly used listening tests designed to obtain reliable ratings of the quality of processed speech from human listeners. Considerations for conducting successful subjective listening tests are given along with cautions that need to be exercised....

This paper seeks to provide an approach to subjective video quality assessment in H.264/AVC standard. In general, methods for video content quality evaluation can be divided on objective and subjective one. While objective methodology uses mathematical methods for presenting human visual system (HVS), subjective method uses group of subjects (observers) to present decoded video sequences. Video...

introduction: radioisotope scanning is the best method for objective assessment of salivary gland function. thus, it was used in a randomized trial of concomitant pilocarpine for assessment of radiation-induced xerostomia, in addition to subjective evaluation by an approved questionnaire and objective standard xerostomia grading. methods: patients randomized in placebo-controlled trial of piloc...

vesicoureteral reflux (vur) is a relatively common and important entity in children. vur can expose patient to risk of pyelonephritis, permanent renal damage or scar. vur itself has no deleterious effect on kidney parenchyma until the development of infection or increased intravesical pressure.   the diagnosis of vur could lead to appropriate therapy and prevention of long term complications. t...

There is a great demand to assess video quality transmitted in real time over packet networks, and to make this assessment in real time too. Quality assessment is achieved using two types of methods: objective or subjective. Subjective methods give more reliable results than objective methods; the latter do not always correlate well with human perception. Unfortunately, subjective methods are n...

The new era of digital communication has brought up many challenges that network operators need to overcome. The high demand of mobile data rates require improved networks, which is a challenge for the operators in terms of maintaining the quality of experience (QoE) for their consumers. In live video transmission, there is a sheer need for live surveillance of the videos in order to maintain t...

OBJECTIVES The aims of the study were to temporally and externally validate the diagnostic performance of two logistic regression models containing clinical and ultrasound variables in order to estimate the risk of malignancy in adnexal masses, and to compare the results with the subjective interpretation of ultrasound findings carried out by an experienced ultrasound examiner ('subjective asse...

BACKGROUND Sleep pattern is an important factor in a child's mental, behavioural and physical status. To evaluate the sleep patterns of children, subjective tools such as sleep logs and questionnaires are still widely used in addition to objective methods of sleep assessment. Despite the established correlation between subjective and objective sleep variables, the characteristic features of sub...
