چکیده

∗ This work is done while the author visiting Microsoft Research China. ABSTRACT The shot based classification and retrieval is very important for video database organization and access. In this paper we present a new approach ‘Nearest Feature Line – NFL’ used in shot retrieval. We look key-frames in shot as feature points to represent the shot in feature space. Lines connecting the feature points are further used to approximate the variations in the whole shot. The similarity between the query image and the shots in video database are measured by calculating the distance between the query image and the feature lines in feature space. To make it more suitable to video data, we improved the original NFL method by adding constrains on the feature lines. Experimental results show that our improved NFL method is better than the traditional classification methods such as Nearest Neighbor (NN) and Nearest Center (NC).

Unsupervised Video Shot Detection Using Clustering Ensemble with a Color Global Scale-Invariant Feature Transform Descriptor

Scale-invariant feature transform (SIFT) transforms a grayscale image into scale-invariant coordinates of local features that are invariant to image scale, rotation, and changing viewpoints. Because of its scale-invariant properties, SIFT has been successfully used for object recognition and content-based image retrieval. The biggest drawback of SIFT is that it uses only grayscale information a...

Evaluation of key frame-based retrieval techniques for video

We investigate the application of a variety of content-based image retrieval techniques to the problem of video retrieval. We generate large numbers of features for each of the key frames selected by a highly effective shot boundary detection algorithm to facilitate a query by example type search. The retrieval performance of two learning methods, boosting and k-nearest neighbours, is compared ...
