Abstract-We present a key frames selection algorithm based on three iso-content principles (Iso-Content Distance, Iso-Content Error and Iso-Content Distortion), so that the selected key frames are equidistant in video content according to the used principle. Two automatic approaches for defining the most appropriate number of key frames are proposed by exploiting supervised and unsupervised content criteria. Experimental results and the comparisons with existing methods from literature on large dataset of real-life video sequences illustrate the high performance of the proposed schemata.
In REF , the authors proposed two automatic approaches to estimate the very suitable number of keyframes by supervised and unsupervised discovering of content of video.
