- Background and objectives
- The objective of the PIV Challenge initiative is to provide timely assessment of the current state of the art of Particle Image Velocimetry methods, including but not limited to, algorithms, optical configurations, and applications. Through well designed test cases, specific aspects, challenges and limitations of the method are targeted, and through detailed comparisons between contributed results, strengths and weakness of the method, as a whole, are explored. Hence, the PIV Challenge results can be used to guide future development efforts and identify new directions for the continuous evolution of the PIV method and growth of the PIV community.
- The PIV challenge is not a competition and it does not identify winners or losers. Instead it is a community instrument used to bring together PIV developers and users in an effort to improve the quality and utility of this powerful and widespread experimental fluid mechanics tool.
- The PIV Challenge has been held in 2001, 2003 and 2005 to exchange the knowledge of the PIV image analysis techniques. In each instance, many teams around the world contributed to analyze the PIV images provided by the organizers. Based on comparisons of the contributed results, characteristics of the PIV evaluation algorithms have been discussed.
