  Statistical processing of speckle data enables observation of speed of
processes. In intensity-based pointwise dynamic speckle analysis, a map related
to speed's spatial distribution is extracted from a sequence of speckle
patterns formed on an object under coherent light. Monitoring of time evolution
of a process needs storage, transfer and processing of a large number of
images. We have proposed lossy compression of these images using JPEG and
JPEG2000 formats. We have compared the maps computed from non-compressed and
decompressed synthetic and experimental images, and we have proven that both
compression formats can be applied in the dynamic speckle analysis.
