rt-utils VS medicaldetectiontoolkit

I am trying to make masks from CT contours and need some help. I am using the rt_utils extension: https://github.com/qurit/rt-utils. I am having issues with the dicom_series_path - I set my path to be the folder all of the dicom slices are housed in, but I get "permission denied" as the function is looking for a file, not a folder. I then set the path to go directly to the first CT slice, and the function runs but creates an error due to there being no contour on that slice (understandable).

Checkout https://github.com/MIC-DKFZ/medicaldetectiontoolkit, they have a recent 3d rcnn implementation. Their paper is a good start on the topic. Also have a look at nnDetection from the same group, it might provide some more leads. Hth

I'm doing research in the area of biomedical image processing using deep learning. At the moment, I'm focused in the detection of biological structures in 3D microscopy images. For this task I trained a Faster R-CNN architecture, however I noticed that while the training loss is decreasing the validation loss is high, doesn't decrease and sometimes oscillates. When I looked at the results, the bounding boxes in the training and validation sets were too small but located at random spots. At first I thought that I should adjust the size of the anchors, however, even after trying different anchor sizes the results didn't improve. I would like to know if anyone has experience in working with 3D Faster R-CNN that could help me with suggestions for this project. (btw, I'm using the code available in this repo). Thanks in advance.
