This document summarizes an article from the International Journal of Electronics and Communication Engineering & Technology. The article discusses content-based image retrieval (CBIR) techniques and face recognition methods for face-based image retrieval. CBIR uses features like color, shape and texture to automatically match images without manual annotation. Face-based retrieval combines CBIR and face detection/recognition to find images of a person based on a query image. The document reviews different CBIR and face recognition approaches, discussing their advantages and limitations. It aims to provide background for future work in face-based image retrieval.
