Implementation of random parameter filtering using OpenMP

This paper proposes the use of OpenMP for random parameter filtering. The use of large numbers of samples during ray tracing rendering results in high quality images yet requires long processing times. On the other hand, the use of a small number of samples results in noise. For the purposes of reducing processing time and removing noise, this study undertook rendering using a small number of samples and subsequently undertook random parameter filtering. In order to speed up the process of random parameter filtering, this study applied OpenMP. The use of OpenMP resulted in a 5.8 times greater improvement in performance.
