Hi, thanks a lot for your great work! I am trying to run this code on my own recording and encountered the same error mentioned in #16 with

OpenCV Error: Assertion failed (scn == 3 || scn == 4) in cvtColor

I guess this is related to color space conversion in your library. I am wondering whether you enforce the 16bit depth to be saved in some specific shape, e.g. [H, W, C] which must be 3-dimensional even C=1?

Any suggestion will be appreciated! Thanks

Thanks for your work of G2LTex. I am following this work. There is an issue about the data. Would please tell me what the 12 figures in .cam file means? The first nine figures is the rotation matrix? Or the fourth, eighth, and twelfth figure combine as the translation vector?

I am looking forward for your reply. Thanks for your time.

Hello,I meeting a problem as follows,I kept all the input formats consistent with the author. I don't know what could be a bug.I am new at it,if you give me some suggesions ,i will be appricate it . (The example given by the author can run through.)

The command line information is as follows： ``Reading PLY: 854151 verts... 281965 faces...PLY Loader: Ignoring face with 5 vertices! PLY Loader: Ignoring face with 5 vertices!

Hi. Thank you for your great work. It's really interesting and helpful. I am trying to run your program with your test data and I am getting the following error: num_views:219 982349 total edges. 371352 faces have not been seen by a view. Saving model... done. loading face info ... G2LTex: tex/texture_view.cpp:195: void tex::TextureView::get_face_info(const Vec3f&, const Vec3f&, const Vec3f&, tex::FaceProjectionInfo*, const tex::Settings&) const: Assertion `valid_pixel(p1) && valid_pixel (p2) && valid_pixel(p3)' failed. Aborted What should I do to make everything work smoothly?

Is the repo executable on Ubuntu 18? Getting shared library errors on executing the code: ./G2LTex ../Data/bloster/textureimages ../Data/bloster/bloster.ply Errors:

1. ./G2LTex: error while loading shared libraries: libopencv_core.so.2.4: cannot open shared object file: No such file or directory
2. ./G2LTex: error while loading shared libraries: libG2LTex.so.1: cannot open shared object file: No such file or directory Is this due to ubuntu version?

Hi, I managed to run G2LTex successfully on my data, but I have a few questions. I end up with several textured meshes with one or more texture files per mesh, the biggest ones being 1024*1024.

• Is there a way to generate bigger textures, e.g. 2048*2048? Is it a fixed dimension, or does it depend on input data?
• Also, given the atlas computation is part of your method, I suppose it's not possible to provide my own texture atlas?
• My mesh is only partly textured, some small parts are left black (not covered by the atlas maybe?), Do you know what might be causing this?
• Finally, it is not clear to me what the different output meshes are (result_label, G2LTex, and orgTexSelection). Could you provide some explanation? In my case, orgTexSelection gives the best result.

Thank you for your help.

Thanks for your work, I have installed libjpeg-dev and libpng12-dev, but it output "Could not load image header of ../Data/bloster/textureimages/color_00.jpg" "Cannot determine image format" when I run the program. Do you know why this happens ？
