Subjective relevance of objective measures for spatial impression

The Perceptual Relevance of Extant Techniques for the Objective Measurement of Spatial Impression

Research into the subjective attributes that contribute to the perceived spatial impression of concert hall acoustics and the objective measurements that may relate to these has been in progress for a large number of years. From this, it has been broadly agreed that spatial impression consists of apparent source width (ASW) and listener envelopment (LEV). However, despite the research that has ...

Objective and Subjective Measures of Diversity :

Website Complexity: Objective versus Subjective Measures

Site complexity has been defined both as a single construct and as multi-dimension construct and operationalized in terms of objective measures or user perceptions. In this research, we distinguish between objective and subjective (perceived) site complexity and examine the relationship between the two. Objective site complexity is measured by how varied a website is; subjective site complexity...

Comparing objective and subjective error measures for color constancy

We compare an objective and a subjective performance measure for color constancy algorithms. Eight hyper-spectral images were rendered under a neutral reference illuminant and four chromatic illuminants (Red, Green, Yellow, Blue). The scenes rendered under the chromatic illuminants were color corrected by 5 color constancy algorithms that are based on zero-, firstand second-order image statisti...

Correlational Analysis of Objective and Subjective Measures of Cataract Quantification.

PURPOSE To evaluate whether correlations exist between objective and subjective measures of vision quality as a consequence of cataract and whether this may qualify the Objective Scatter Index as a supplementary means of cataract assessment. METHODS A prospective multicenter, cross-sectional study was conducted in 10 centers across France in patients undergoing cataract extraction surgery (le...
