DETECTION OF CIRCULAR ARCS FOR CONTENT-BASED RETRIEVAL FROM AN IMAGE DATABASE

Methods are discussed for producing a summary of geometric content for images from a specific geological application, which can be used for content-based retrieval of interesting images from a large database. U sing a data set of 100 images, it is shown that a local arc detection scheme provides a more concise and hence a better summary of image con tent than a conventional edge map, while giving a superior performance .
