• Developed functions to load images, apply Gaussian blurring, adaptive thresholding, and bilateral filtering for achieving smooth edges and vibrant colors.
• Enhanced the output images' vibrancy and smooth shading transitions to closely mimic traditional anime art styles.
• Included functionality to display the original and transformed images side by side for easy comparison.
• Added documentation files, including README.md, requirements.txt, and LICENSE.md, to provide project details, dependencies, and licensing information.
