Abstract - Cartoonizing photos is a fascinating part of digital image processing. This research explores picture cartoonification methods and uses sophisticated machine learning models and algorithms to automate and improve data transformation. The main goal is to investigate and evaluate methods for creating high-quality cartoon effects while maintaining picture information. For effective colour quantization, K-Means clustering minimizes picture colours for visual simplicity and brightness. Edge detection with adaptive thresholding defines cartoon characteristics by detecting crisp edges and outlines. Specialized stylization processes enhance creative expression in altered pictures, giving each output a distinct and attractive style. Parameter optimizationandalgorithmicfine-tuningimprovecartoonified output quality, consistency, and style coherence. The results demonstrated a high accuracy rate of 92% for color quantization and 89% for edge detection. Additionally, user feedback indicated satisfaction with the quality and consistencyofthegeneratedcartoonimages.Integrationwith the Imagine API further enhanced the system's usability, providing real-time processing and a user-friendly interface. Overall, this research presents a novel approach to image cartoonification, offering both computational efficiency and high-quality outputs. The findings highlight the potential of applying machine learning to creative processes, paving the way for future innovations in digital image transformation.
