简介：多尺度的策略在基于波形的速度倒置的成功的申请是很重要的。策略顺序preceeds从长当模特儿突然速度可伸缩，很好在完整的波形倒置(FWI)被开发了解决本地mininum问题。相反，它的不好在图象域波形断层摄影术(IWT)理解，哪个幕後放映的影像普通图象的支离破碎的波形部件聚在一起进速度更改。IWT对本地最小的问题不太敏感，但是趋于与低分辨率造长规模的模型。以便由IWT造长规模、短规模的模型，我们讨论在图象域限制的几多尺度的策略。策略包括模型reparameterization，客观功能切换和重新可伸缩的坡度。Marmsousi模型和真实数据上的数字测试证明我们的建议多尺度的IWT在有宽wavenumber光谱的buidling速度模型是有效的。
