Removing the Stripe Noises Interference on the Hα Full-Disk Solar Image Based on Multiscale Transform

Abstract:

Hα full-disk observation is an important observation of the sun. It has an important significance to the solar physics research. But its observation process may be affected by the system, resulting the observed images contain stripe noises. This paper describes a method to remove the particularity of stripe noises contained in the Hα full-disk solar image. This method includes the following four steps: First, decomposing the sun image into multiple detail scales by the multiscale transform; Second, doing special two-dimension signal conversion on the detail scales mainly containing the noises signal; Third, doing the adaptive Gaussian filtering on the two-dimension signal and restoring the processed signal to the image; Finaly, using the multiscale inverse transform to obtain the final restoration image. Experiments show that this method can effectively remove this type of noise interference from the solar image and improve the quality of the solar image.
