 The WNet3D is designed to segment objects based on their brightness, and is particularly well-suited for images with a clear contrast between objects and background.
 
-The WNet3D is not suitable for images with artifacts, therefore care should be taken that the images are clean and that the objects are at least somewhat distinguishable from the background.

     For optimal performance, the following should be avoided for training:
 
     - Images with very large, bright regions

     - Uneven brightness distribution
     - Varied object shapes and radius
-    - Noisy images
+    - Noisy images (as long as resolution is sufficient and boundaries are clear)
     - Uneven illumination across the image
 
 For optimal results, during inference, images should be similar to those the model was trained on; however this is not a strict requirement.

 - **Reconstruction (decoder) performance is poor** : First, try increasing the weight of the reconstruction loss. If this is ineffective, switch to BCE loss and set the scaling factor of the reconstruction loss to 0.5, OR adjust the weight of the MSE loss.
