Gamma Correction:
    Adjusts the brightness and contrast of the blended image for enhanced clarity and visibility.

Input and Output:
    Processes an input image and generates a contour-accentuated version as the output.

Python 3.x
Libraries:
    numpy
    opencv-python

Prepare Your Image:
    Place the input image (e.g., input.jpg) in the same directory as the script or update the input_image_path variable with the full path to your image.

Run the Script:
    Execute the script:

python CAT.py

Adjust the gamma parameter in the adjust_gamma() function to fine-tune the brightness and contrast:

    img_gamma = adjust_gamma(img_blend, gamma=0.5)  # Example gamma adjustment

render(img_rgb):
    Applies grayscale conversion, Gaussian blur, and blending for initial contour enhancement.
adjust_gamma(image, gamma=1.0):
    Performs gamma correction to optimize contrast and brightness.
Main Script:
    Reads the input image, applies the CAT process, and saves the output image.
