Hi, thank for your share. I meet the bug when I run the code: "python3 -m flowmap.overfit dataset=images dataset.images.root="/xxx/flowmap/mipnerf360_garden"" Do you have any method to solve it? ![image](https://github.com/dcharatan/flowmap/assets/70420660/d4c41106-5f01-44fb-bb22-111b6dc2421e) ![image](https://github.com/dcharatan/flowmap/assets/70420660/41f92bde-73b4-4962-91c5-9ca214c19dcb)

My application scenario involves using a standard `PINHOLE` camera cropped from a fisheye camera. Can `flowmap` fix the intrinsic parameters without optimization, solely used for estimating depth and pose information?...

Could your code generate a transform matrix that can be used in other Nerf frameworks or methods, such as Nerfstudio or Neuralangelo? These methods require a transform matrix in JSON...

Does this code support images from anamorphic lenses? Would the intrinsic data be calculated correctly? Also, how many parameters are returned for the distortion matrix? Thanks!

Hello, I successfully ran the subsampling preprocessing script, however when i run the overfit script: ```python3 -m flowmap.overfit dataset=images dataset.images.root=/.../.../.../.../flowmap/frames``` ``` Computing RAFT flow: 100%|███████████████████████████████████████████████████████████████████████████████████████████████████████████████| 18/18 [00:43

Hi, I run the following command and generated images/ply in outputs/local folder successfully, I just have a question: I saw the novel synthesis view videos from your website cameronosmith.github.io/flowmap: could...

Great job! Could you please share the models related to paper/assets/exports_birds_compact.pt and paper/assets/flows_tracks_birds_compact.pt? These two pt files are missing when running render_point_cloud. py under paper directory. May I ask where...
