虽然a等人最近采用VFI插值出与图像行数目相同的RS frames来采样出一个GS proposal但并未从本质上建立VFI和RS-based VR之间的联系导致了巨额的计算且不能时间任意GS恢复。把这句话翻译成英文

Although the recent approach of using VFI interpolation by a et al. to sample RS frames that are the same as the number of image rows for GS proposal, the essential connection between VFI and RS-based VR has not been established, resulting in a significant amount of computation and inability to recover GS at any time.
