HIP MRI VQVAE and PIXELCNN implementation into recognition folder

[BHUP-UQ]

Student 48036177

Created Hip_MRI_VQVAE_PixelCNN folder in recognition as assignment submission. Apologies for scuffed git history, I originally made all changes in local repo and had to do a bunch of commits (including renaming) to get the files to the right branch while bringing the commit history.

File Organizing:

• Please organize all the custom files, including README, images, code scripts and other files, in your project folder at "/PatternAnalysis-2025/recognition/custom_folder_with_project_name_and_SNum". All other files should remain unchanged in their original locations.
• Merge problem from wrong pull request at last year's repo.

Problem Solving:

• For some reason, the main() function is commented out in the script, which prevents the model from being trained. In addition, the testing code loads the same pre-trained weights (trainer.weights.h5) as the initial weights used before training, indicating that the model was not trained properly.
• The reported SSIM is 0.78039; however, no supporting evidence is provided. In addition, the visualized outputs appear unreasonable, suggesting that the SSIM value should not be this high.

Model and functions:

• It correctly uses TensorFlow to construct the VQVAE models and functions. However, failed to train it.
• Good data augmentation.
• Properly use the train/validation/test datasets.

Code design: The source scripts were transformed with limited success.

Code comment and docstring:

• Good code comments
• Good function docstrings
• NO header block

Difficulty: Hard.

Additional Comments:

• Good commits
• The README design can be more structured and provide more comprehensive content. Since this is a report, a proper Discussion and Conclusion section is also expected to clearly summarize your project.
