Image quantization is a way to simplify images by reducing the number of colors while keeping them looking the same. This paper suggests a new method that combines two techniques, Social Spider Optimization (SSO) and K-Means clustering, to make this process faster and better image quantization. SSO is like how social spiders work together to find food. It helps K-Means, which can be slow, get started and finish faster by choosing the right starting points through finding the best centroids. This new way not only speeds things up but also makes the pictures look better. In tests, we tried this SSO-K-Means method on different sets of images and compared it to regular K-Means. The results showed that using modified SSO with K-Means improved image quality and made the process faster. This method could be useful in tasks like image compression, retrieval, and other image jobs where simplifying pictures is important.
