Area-based matching is a common procedure in various fields such as fluidics, image-based measurements, and stereo image processing. Sub-pixel estimation using parabola fitting over three points with their similarity measures is also a common method to increase the resolution of matching. Some investigations or studies concerning the characteristics of this estimation have been reported.
In this report, we applied our new algorithm reducing sub-pixel estimation error to the PIV standard images. This method is independent from the similarity measure and quite simple to implement. The results indicate the advantage of our novel method.
