In this study, the wavelet-based JPEG2000, the next generation image compression technique was applied to PIV for efficiently reducing the physical storage and the noise in images. For evaluating the relationship between image parameter and compression ratio, the PIV standard images were compressed by JPEG2000 and JPEG. It was found that the superior performance of JPEG2000 as compared to JPEG at any compression ratio. JPEG2000 method performs beyond compression ratios where JPEG breaks down, enabling compression of high-resolution PIV images.
