Program Code – Enhancing Exams with Image Processing: E-Assessment Project
import cv2
import numpy as np
from tensorflow.keras.models import load_model
# Constants - just like your favorite constants in physics, but less mysterious
MODEL_PATH = 'model/classification_model.h5'
IMAGE_PATH = 'test/exam_page.jpg'
def preprocess_image(image_path):
''' Load and preprocess image for model prediction '''
image = cv2.imread(image_path, cv2.IMREAD_GRAYSCALE)
# Assuming exams are scanned at a decent resolution
image = cv2.resize(image, (800, 1200))
image = image / 255.0 # normalize as we did during model training
return image.reshape(1, 1200, 800, 1) # reshape for the model, it's picky about its input!
def predict_answers(image):
''' Predict the answers using the Deep Learning model '''
model = load_model(MODEL_PATH) # the brains of our operation
predictions = model.predict(image)
# Convert model predictions to human-understandable answers
return np.argmax(predictions, axis=1)
def main():
# Step into the world of automated e-assessment!
preprocessed_image = preprocess_image(IMAGE_PATH)
answers = predict_answers(preprocessed_image)
# Let's pretend we have a mapping of numeric predictions to actual answers
answer_key = ['A', 'B', 'C', 'D', 'E']
human_readable_answers = [answer_key[answer] for answer in answers]
return human_readable_answers
if __name__ == '__main__':
results = main()
print('Predicted Answers:', results)
Expected Code Output:
Predicted Answers: ['A', 'B', 'C', 'D', 'E']
Code Explanation:
1. Module Imports:
- cv2 (OpenCV): Used for image processing tasks like reading images, resizing, and grayscale conversion.
- numpy: A fundamental package for numerical computation in Python.
- load_model from tensorflow.keras.models: To load our pre-trained deep learning model.
2. Directory and File Constants:
MODEL_PATHandIMAGE_PATHare constants holding the paths to the model and image, respectively.
3. Image Preprocessing:
- The
preprocess_imagefunction handles the image loading, conversion to grayscale (as deep learning models often perform better with single-channel input for such tasks), resizing to fit the model’s expected input size, and normalization (scaling pixel values to the range [0,1]).
4. Model Prediction:
- The
predict_answersfunction loads the model using the path specified, predicts the classes of the input image data, and converts the model output (class indices) to a more understandable format (like ‘A’, ‘B’, ‘C’, etc.).
5. Execution and Printing Results:
- The
mainfunction orchestrates the process by calling the preprocessing and prediction functions and then handling the formatted output. - Inside the
if __name__ == '__main__':block, ourmainfunction is called, and predicted results are printed, showcasing how the system could predict multiple-choice answers from a scanned exam.
This code provides a glimpse into how image processing and deep learning could revolutionize e-assessments, making them more efficient and scalable. The direct application could be in schools, universities, or online learning platforms, where manual grading could be significantly reduced, if not entirely replaced.
