Paper Abstract

Pressure sensitive paints are used to record surface pressures on wind tunnel models at high spatial resolution. Images taken at two separate pressure conditions are ratioed to yield quantitative measures of surface pressures. However, these two images have very different intensity values. This paper discusses some common motion estimation techniques, such as block matching algorithms and point correspondences, that were used to analyze this intensity variant image set. The drawbacks and limitations to each method are presented as well as any modifications that were necessary to implement each method given an intensity variant data set. Comparisons between different methods or implementations are discussed in terms of the speed of computation and the accuracy of the motion compensated result.
