Research on Semantic Extraction of Content-based Video Retrieval;

The analysis of the remotely sensed images evolves in three stages: physical classification, semantic extraction, and information recognition.

By means of the paradigms of high speed word classifying, sentence verification and high speed picture classifying, the paper investigated the effect of ways of linguistic expression on the semantic recovery time of natural concepts.

By means of the paradigms of word high speed classifying, sentence verification and picture high speed classifying, the present study explored the effect of the ways of linguistic expression on the semantic recovery time of scientific concepts.
