An objective singing evaluation approach by relating acoustic measurements to perceptual ratings
This paper presents an objective singing quality evaluation approach based on a study of the relationship between acoustic measurements and perceptual ratings of singing voice quality. Individual perceptual criteria’s contributions to the overall rating are also investigated to find significant evaluation terms. Experimental results show that critical perceptual criteria for singing evaluation ...
متن کاملRate-perceptual-distortion optimization (RpDO) based picture coding - Issues and challenges
Perceptual image and video coders have been reported extensively in the literature with a recent survey listing sixteen representative PVCs (perceptual video coders) for single-view video coding, ten of which conform to H.263, MPEG-4 or H.264/AVC international standard. Successful approaches to perceptual picture coding are classified as perceptual predictive coding, perceptual quantization, ra...
متن کاملObjective and Subjective Measuruments for Video Compression System
In this paper the extent to which the quality of video signal is degraded by process of compression and decompression is considered. Traditional objective video signal quality measurements based on static test signals are not able to characterise the picture degradation due to compression and decompression. These measurements are indirect and resulting distortions of test signals determine vide...
متن کاملPerceptual video quality assessment in H.264 video coding standard using objective modeling
Since usage of digital video is wide spread nowadays, quality considerations have become essential, and industry demand for video quality measurement is rising. This proposal provides a method of perceptual quality assessment in H.264 standard encoder using objective modeling. For this purpose, quality impairments are calculated and a model is developed to compute the perceptual video quality m...
متن کاملSemantic processing survey of spoken and written words in adolescents with cerebral palsy: Evidence from PALPA word-picture matching test
Objective: The present study aimed to assess and compare semantic processing of spoken and written words in adolescents with cerebral palsy and healthy adolescents. Method: The present study is quantitative in terms of type and experimental in terms of method. Examination Group consisted 30 adolescents with cerebral palsy aged 10 to 15 years were selected by convenience sampling method. All of ...
