应该就是过滤杂波的

这个不知道能不能帮上忙，你看看有没有用
Helicon Filter， also referred to as Helicon， Filter， or as HF， is a proprietary commercial and freeware photo editing software program for Microsoft Windows， similar to such programs as Adobe Photoshop and the open source GIMP， developed and published by Helicon Soft Ltd. Unlike these other programs， Helicon Filter is designed primarily to edit and improve existing photos and not for graphics creation. Helicon Filter's interface also differs from other programs in that compact toolbars and menus containing editing tools are replaced with labeled "filter" tabs， each tab containing labeled edit options specific to a single aspect of the picture. Although some editors used to Photoshop-style programs may initially find this layout unfamiliar and unlike the standard toolbar layout， beginners and those who don't recognize the standard icons generally find this very helpful for getting through the editing process.
