This document provides a comprehensive survey on Content-Based Image Retrieval (CBIR), discussing methodologies for extracting visual features such as color, texture, and shape for effective image classification and retrieval. CBIR is presented as an alternative to traditional text-based image retrieval methods that are often inefficient and time-consuming. The paper emphasizes the advancements in techniques like support vector machines (SVM) and cascaded SVM in enhancing retrieval performance across various applications.
