Abstract :
Under the environment of rapid development of computer network technology, digital image resources more and more rich, how effective organization, management and use of increasingly large image database, become an urgent problem to explore. Achieve fast and efficient retrieval image is the key content of digital image using, breakthrough the traditional retrieval technology present situation of high input and low efficiency of manual, you need to set up the whole horizon, the knowledge map of indexing and retrieval procedure. This article mainly from the high dimensional indexing technology, knowledge and semantic technology to explore and discuss the text-based keywords retrieval and retrieval based on image content of two kinds of technology implementation, expectations for the user to quickly find interested image provide theoretical guidance and practical technology, image retrieval technology to lay the foundation for the future.
