Interactive Image Matting

This is an interactive image matting program developed using MATLAB, featuring multiple advanced algorithms including Poisson matting, Hillman's approach, and Ruzon's method along with their corresponding source images. These sophisticated algorithms employ different mathematical frameworks - Poisson matting uses gradient domain processing, Hillman's method implements probabilistic models, while Ruzon's approach utilizes statistical color sampling techniques - to achieve precise foreground extraction. The program enables users to select appropriate matting methods based on their specific requirements and perform real-time interactive adjustments using source images to optimize matting results. The implementation includes GUI components for user interaction, alpha matte computation modules, and color blending functions to ensure extracted foregrounds appear natural and realistic. Designed with an intuitive interface and comprehensive documentation, this program is accessible to both professional image processing specialists and beginners, featuring modular code structure that allows easy integration of additional matting algorithms.
