A Nll-based and Feature Extraction Supported Shot Retrieval Approach
Nearest Feature Line (NFL) is a convenient and effective way to search in video database,but the Framework does not address the feature extraction for dimension reduction.In this paper,a novel method is proposed for content-based shot retrieval.Karhunen Loeve Transform (KLT) is used to reduce dimensionality of feature spaces.In addition,we present a new take-maximum-from-minima (TMFM) based key frame extraction algorithm,and key-frames extraction is combined with the NFL method to achieve a better performance.Experimental results have shown that our combined method not only achieves superior performance than the NFL and Equal interval (EI),and other classification methods such as Nearest Neighbor (NN) and EI and Nearest Center (NC) and EI but also increases the retrieval speed and reduces the memory significantly without sacrificing the retrieval accuracy.
