Training an Object Detection Model

Let us see an instance of manually training an object detection pipeline. Below we use a pre-trained AutoImageProcessor on the input image and an AutoModelForObjectDetection for object detection.

# Load the pre-trained AutoImageProcessor for image preprocessing
image_processor = AutoImageProcessor.from_pretrained("MariaK/detr-resnet-50_finetuned_cppe5")

# Load the pre-trained AutoModelForObjectDetection for object detection
model = AutoModelForObjectDetection.from_pretrained("MariaK/detr-resnet-50_finetuned_cppe5")

# Perform inference on the input image
with torch.no_grad():
    # Preprocess the image using the image processor and convert it to PyTorch tensors
    inputs = image_processor(images=image, return_tensors="pt")
    # Forward pass through the model to obtain predictions
    outputs = model(**inputs)
    # Calculate target sizes (image dimensions) for post-processing
    target_sizes = torch.tensor([image.size[::-1]])
    # Post-process the object detection outputs to obtain the results
    results = image_processor.post_process_object_detection(outputs, threshold=0.5, target_sizes=target_sizes)[0]

# Iterate over the detected objects and print their details
for score, label, box in zip(results["scores"], results["labels"], results["boxes"]):
    # Round the box coordinates to 2 decimal places for better readability
    box = [round(i, 2) for i in box.tolist()]
    # Print the detection details
        f"Detected {model.config.id2label[label.item()]} with confidence "
        f"{round(score.item(), 3)} at location {box}"

Plotting Results

We will now add bounding boxes and labels to the detected objects in the input image:

# Create a drawing object to draw on the image
draw = ImageDraw.Draw(image)

# Iterate over the detected objects and draw bounding boxes and labels
for score, label, box in zip(results["scores"], results["labels"], results["boxes"]):
    # Round the box coordinates to 2 decimal places for better readability
    box = [round(i, 2) for i in box.tolist()]
    # Extract the coordinates of the bounding box
    x, y, x2, y2 = tuple(box)
    # Draw a rectangle around the detected object with a red outline and width 1
    draw.rectangle((x, y, x2, y2), outline="red", width=1)
    # Get the label corresponding to the detected object
    label_text = model.config.id2label[label.item()]
    # Draw the label text on the image with a white fill
    draw.text((x, y), label_text, fill="white")

# Display the image with bounding boxes and labels
