Abstract :
The authors propose a language, called Hierarchical Temporal Logic (HTL), for specifying queries on video databases. The language is based on the hierarchical as well as temporal nature of video data. They give similarity based semantics for the logic, and give efficient methods for computing similarity values for subclasses of HTL formulas. Experimental results, indicating the effectiveness of the methods, are presented
