Failed to get the superpoint of Replica

Hi @intro965, We provide the processed Replica dataset [here](https://github.com/VinAIResearch/Open3DIS/blob/main/docs/DATA.md). Best.

Inconsistent number of frames in the given validation scannet200 scene and rendered scene.

Hi @Yebulabula, We capture RGB-D frames at intervals of 5, indicating that we record and append the results to the self.frames list every 5 invocations of this class constructor: [here](https://github.com/ScanNet/ScanNet/blob/master/SensReader/python/SensorData.py#L73)...

Inconsistent number of frames in the given validation scannet200 scene and rendered scene.

Hi @Yebulabula, **A1:** For post-processing techniques, you can explore various NMS algorithms at [ISBNet](https://github.com/VinAIResearch/ISBNet/blob/master/isbnet/model/model_utils.py), filtering techniques at [OVIR-3D](https://github.com/shiyoung77/OVIR-3D/blob/main/src/proposed_fusion.py#L164C5-L164C34), DBScan at [Segment3D](https://arxiv.org/pdf/2312.17232) and many other heuristic algorithms... **A2:** Certainly, you can...

Testing Open3DIS on ScanNet200 dataset with Mask3D?

Hi @whuhxb, We have also tested Open3DIS with Mask3D, detailed results are presented at our [project page](https://open3dis.github.io/) We are planning to upload the code for Mask3D 3D proposal generation in...

code for the ScanNet++ dataset

Hi @LiangXu123, Training the 3DIS network for ScanNet++ is a bit challenging for ISBNet as we are investigating proper hyperparams best suited for ScanNet++. ISBNet pretrained on ScanNet200 yields worse...

Format data input for refine_grounding_feat.py

Hi @caodinhduc, Currently, we just provide sample data for ScanNet200 and ScanNet++, Replica, and S3DIS. We believe it's pretty straightforward and easy to follow in the Data Preparation section. Besides,...
