Abstract
With the emergence of much video, video content retrieval becomes an active research direction in the multimedia applications. Most of the existing video retrieval technologies are based on low-level features. These features are quite different from the semantic concepts. It seriously influences the practicality of the video content re- trieval system. The gap between low-level features and high semantics is difficult to narrow, so how to extract se- mantic concepts in the human thought from video is becoming a most challenging research of the video content retriev- al. This paper introduces the background of semantic video retrieval and the latest and dynamic research at home and abroad, analyzes the advantages and disadvantages of the existing methods and summarizes the existing key technolo- gles关键词
