There are some wrong samples in the dataset

[pfdu]

Some images in the data set are wrong, for example, scene_00001_906324_1.png in the target_image folder in PNVS easy, the image is completely black. In addition, there are some similar error samples.

source_image/scene_00001_906324.png

target_image/scene_00001_906324_1.png

In some samples, there is no floor in the house, for example, scene_00008_914963.png in the source_image folder in PNVS easy.

@pfdu There are indeed some bad rendered images in the dataset. We have manually filtered out most of the bad samples, but mainly focus on the hard set on account of its difficulty (after filtering the samples in the hard set was reduced from 62578 to 19940). It's a very tough task to manually filter all images, thus we only preprocessed the easy set simply since the camera motions are relatively small and the performance will not be influenced tremendously. As for the no-floor source images, they are from the original Structured3D dataset, and we do not have an effective way to test whether the source image has corrrect floor or not when rendering target views for it. We are sorry for that.
