Project 5: Multimodal Medical Image and Report Analysis with Vision-Language Models
Step 4: Generate Captions for Medical Images
Now we'll enhance our system to automatically generate descriptive captions for medical images. This crucial functionality involves modifying our existing pipeline to create detailed, accurate textual descriptions of medical imagery.
The caption generation process leverages our trained model's understanding of medical visual features and converts them into coherent, clinically relevant text descriptions. This capability is particularly valuable for standardizing reporting procedures, reducing documentation time, and ensuring consistent interpretation of medical images across different healthcare providers.
def generate_caption(image):
inputs = processor(text=["A medical image"], images=image, return_tensors="pt")
outputs = model(**inputs)
logits_per_image = outputs.logits_per_image
probs = logits_per_image.softmax(dim=1)
return captions[probs.argmax().item()]
# Generate captions for all images
for i, image in enumerate(images):
caption = generate_caption(image)
print(f"Caption for Image {i + 1}: {caption}")
Let's break down this code that generates captions for medical images:
1. Caption Generation Function
- The
generate_caption(image)
function takes a medical image as input and: - Uses the CLIP processor to prepare both a generic text prompt ("A medical image") and the input image
- Processes these inputs through the model to get similarity scores
- Converts the scores to probabilities using softmax
- Returns the most relevant caption from the existing caption pool
2. Caption Generation Loop
- The code then loops through all images in the dataset to:
- Generate a caption for each image using the function above
- Print the generated caption along with the image number
This functionality is designed to standardize reporting procedures, reduce documentation time, and ensure consistent interpretation of medical images across different healthcare providers.
