Usage of image-filtering techniques in realistic real-time rendering
This article discusses modern real time filtering algorithms for images synthesized by stochastic ray tracing method. The computational complexity of algorithms, until recently, did not make it possible to implement these algorithms for working in interactive applications. However, existing real-time filtering algorithms already show comparable results with non-interactive filters. The text of the article focuses on four algorithms, for which a brief description is given. The paper presents an analysis of algorithms based on image quality metrics. The analysis revealed problems of the algorithms and methods for their solution, and highlighted successful ways to improve the quality of real time filtering.
