This paper describes a computational model for the prediction of perceived spatial quality for reproduced sound at arbitrary locations in the listening area. The model is specifically designed to evaluate distortions in the spatial domain such as changes in source location, width and envelopment. Maps of perceived spatial quality across the listening area are presented from our initial results.

The quality of Internet connections is increasingly important for people’s daily lives as work and access to services move the digital sphere. Likewise, businesses public agencies need rely more on networks service delivery. However, way individuals experience can vary substantially within countries, notably along urban-rural continuum. Measuring such variation in a consistent understand where ...

recent literature attaches high importance to scenic evaluation of natural landscapes. scenic beauty evaluation techniques often use parameters derived from photographs or collected in situ data via field assessment and questionnaires. such techniques are relatively costly and time consuming. park managers and recreational planners require spatial tools and techniques that are fast, flexible an...

Hard red winter wheat (Triticum aestivum L.; HRWW) is broadly grown in Great Plains and northwestern states the United States. Knowing how quality characteristics are correlated across space may help buyers locate grain elevators that have with they need. The objective of this study was to determine spatial pattern factors HRWW. Mixed effects regression modeling used estimate mean for each loca...

Quality metrics, within the field of laser range imaging, are used to quantify by how much some aspect of a measurement deviates from a predefined standard. Measurement quality evaluations are becoming increasingly important in laser range imaging for range image registration, merging measurements, and planning the next best view. Spatial uncertainty and resolution are the primary metrics of im...
