Mean-Shift Based Image Retrieval System

We have implemented a mean-shift based image retrieval algorithm that compares similarity between two images and selects the most closely matched image. The core concept of this algorithm utilizes mean-shift clustering for image processing, followed by similarity calculation through comparison of clustering results. Key implementation aspects include using histogram-based feature extraction for image representation and applying mean-shift with kernel density estimation to identify dominant modes in the feature space. We introduced several optimizations including bandwidth parameter optimization and convergence criteria refinement to enhance both accuracy and computational efficiency. The algorithm employs feature vector comparison methods such as Euclidean distance or cosine similarity to quantify image resemblance. This implementation enables rapid identification of the most similar images within large datasets, providing an effective approach for content-based image retrieval applications. The system architecture includes preprocessing modules for feature extraction, mean-shift clustering components, and similarity measurement functions that work together to deliver robust image matching capabilities.
