Knee Osteoarthritis Analysis

Pipeline of knee osteoarthritis grading pipeline, which includes knee joints detection and knee OA grading.

klg_pipeline

DetJoint

  • Detecting two knee joints in X-ray images using a customized YOLOv2 model.

ClsKL

  • Classifying the KL grade of detected knee joints with a novel ordinal loss.

Data & Models

Knee joint detection (DetJoint) and KL grading (ClsKL) training/testing datasets, as well as best models, can be downloaded from KneeXrayData, around 7G.

gradingkneeoa's Issues

DetJoint Saved Model Weights

Hi PingjunChen! Thanks for the amazing research and keeping everything opensourced!

Im looking through your DetJoint folder for where you've saved your YOLOv2 weights and you seem to save it under "best_models/2wd/det-epoch-490-0.000088.pth" (found this in "DetJoint/test/test_knee.sh")

When looking through the dropbox provided (https://figshare.com/articles/KneeXrayData/8139545) I cant find the subfolder "2wd" under best_models.

Did you perhaps take it down or didn't upload the latest weights?

Many thanks

Dataset OAI

I have requested to access data in the Osteoarthritis Initiative but it takes 2 months from now the website is still not working
can you please share the dataset?

Type Eorror

Hi, I execute your code but appear this error:
type error: can't convert np.ndarray of type numpy.bytes_. the only supported types are: float64, float32, float16, complex64, complex128, int64, int32, int16, int8, uint8, and bool.
Did you meet a similar problem before?
many thanks
