A study of gradual transition detection in historic film material

Abstract

The detection of gradual transitions focuses on two types of approaches: unified approaches, i.e. one detector for all gradual transition types, and approaches that use specialized detectors for each gradual transition type. We present an overview on existing methods and extend an existing unified approach for the detection of gradual transitions in historic material. In an experimental study we evaluate our approach on complex and low quality historic material as well as on contemporary material from the TRECVid evaluation. Additionally we investigate different features, feature combinations and fusion strategies. We observe that the historic material requires the use of texture features in contrast to the contemporary material that in most of the cases requires the use of colour and luminance features.
