AB: The principal objective of this study is to analyze structures inside Coronal Mass Ejections (CMEs) using wavelet technique. We have used the archived public data taken with the SOHO/LASCO coronographs C2 and C3. We have found that different structures that can exist in a CME can be observed at different spatial scales of wavelets. We also look for the direction and orientation of the most intense flux that is present in a CME in the entire image. We intend to use the same wavelet technique to reconstruct the original image and obtain higher contrasts of the image.
