There is an increase in studying the proteome gel images of the same organism under different conditions. Only the multiresolution methods such as wavelet transform are able to cope with both global and local deformations in the images during image registration. Wavelet transform can allow the images not only to be registered but also to be compressed in one process. As a newly developed multiresolution method, complex wavelet transform provides approximate shift-invariant and directionally selective filters. However, it also introduces limited redundancy into the wavelet representation. In this paper, the compression of the proteome gel image from C. elegans is fulfilled using complex wavelet transform and the result is compared with that of original wavelet transform.
