An evaluation of reconstruction filters for a path-searching task in 3D.

Roberts, D. and Ivrissimtzis, I. and Holliman, N. (2014) 'An evaluation of reconstruction filters for a path-searching task in 3D.', in 2014 Sixth International Workshop on Quality of Multimedia Experience (QoMEX 2014) : Singapore, 18-20 September 2014. Piscataway: IEEE, pp. 165-170.


The choice of reconstruction filter used to interpolate between sample points when generating images from volumetric data sets can have an impact on image quality. There are a range of reconstruction filters as well as methods to determine the quality of these filters. While it is well documented that stereoscopy can improve the performance of spatial search tasks, it is not clear how artifacts introduced by the choice of reconstruction filter will impact the performance of these tasks. In this study we report the results of a path-tracing experiment where we assess the effectiveness of stereoscopy and three reconstruction filters in terms of accuracy and response time. Our results suggest that the reconstruction filter can have a significant effect on path-tracing tasks and that stereoscopy can significantly improve accuracy results whilst slightly increasing response time.
