• Developed by: Saidi Souhaieb
• Finetuned from model: YOLOv8

Uses

This model is designed to detect pixelated captcha digits by showing bounding boxes and extracting the coordinates of the detections.

How to Get Started with the Model

from PIL import Image, ImageDraw
from YOLO import YOLO  # Assuming YOLO is a class in a module named YOLO

# Load the model
model = YOLO("models/number_finder.pt")

# Get model results
model_results = model(image_path) 
img = Image.open(image_path)
draw = ImageDraw.Draw(img)

# Sort results based on the x-coordinate
detected_objects = []
captcha_result = ""
boxes_data = []

for result in model_results:
    for box in result.boxes:
        box_data = {"xyxy": box.xyxy[0].tolist(),
                    "label": str(box.cls.item())}
        boxes_data.append(box_data)

sorted_boxes_data = sorted(boxes_data, key=lambda x: x['xyxy'][0])

# Remove similar boxes
unique_sorted_boxes_data = [sorted_boxes_data[0]]
for i in range(1, len(sorted_boxes_data)):
    current_box = sorted_boxes_data[i]
    prev_box = unique_sorted_boxes_data[-1]
    # Check if the current box's x-coordinate is significantly different from the previous box
    if abs(current_box['xyxy'][0] - prev_box['xyxy'][0]) > 1:  # Adjust threshold as needed
        unique_sorted_boxes_data.append(current_box)

for box in unique_sorted_boxes_data:
    label_name = box["label"]
    box_coords = box["xyxy"]
    detected_objects.append((box_coords))
    draw.rectangle(box_coords, outline="red")
    draw.text((box_coords[0], box_coords[1] - 10), label_name, fill="red")
    captcha_result += str(int(label_name[0]) - 2)
img.show()  # Display the image with bounding boxes and labels
