The Feature Related Techniques in Content-Based Image Retrieval and Their Application in Solar Image Data

The paper mainly investigates the widely-used image features and related feature selection methods in content-based image retrieval (CBIR).The texture features and shape features that could be used in the retrieval of solar images are mainly discussed. The result of the survey indicates that although the CBIR related research work in solar image retrieval is comparatively less, the existing achievements still have great instruction for our future work in this domain.
