nyuv2-meta-data's Issues

Is there any instance segmentation label?

In official website it is said Each object is labeled with a class and an instance number. Where is this label stored?

What does eigen means?

What does the eigen named file in test_label means?

Depth / Color intrinsics

I don't find any way to convert depth image to xyz pointcloud.
The resolution is unfamiliar (730 : 530)
Do you have any camera calibration files @ankurhanda

about zero-class

in nyu dataset, If a pixel’s label value is 0, then that pixel is ‘unlabeled’. Is this same in your label image? i check one of them they are in range of 0-12 not 0-13 .

The color value for each class for showing the groundtruth label map

Thanks for you efforts really! I wonder if there is an official color palette for each class so as to show the groundtruth label map. Hope for your answers! Many thanks!

nyuv2 dataset "namesToIds"

How do we get the list of all the classes along with the lDs ? I checked the original .mat (2.8 GB) file but was not able to access it.

Confused about the label in mat file

I open the nyu_depth_v2_labeled.mat file and access its label attribute. When I do a max over the label file, I get 894. How should I extract semantic label from it? Shouldn't label be indexing 0~12 classes?
My final goal is to get the instance segmentation mask, bounding box along with its class label. Can I ask you to recommend any ways to do it? Thank you!

One question about 'camera_rotations_NYU.txt'

Hello! I am confused with one of your file: 'camera_rotations_NYU.txt'. Under my understanding, this file contains 1449 matrices whose index is corresponding to the index of image_data in 'nyu_depth_v2_labeled.mat'. I don't know if my understanding of the index is wrong. Thank U!

test set

Hi Ankur,
Can you please tell me what the difference is between two test set for ground truth? (nyuv2_test_class13.tgz vs. nyuv2_test_class13_eigen.tgz)
Thanks,
Caner
