Abstract
A method for extraction of descriptors from video content, includes the following steps: a Key Frame Extracting step, applying a local descriptors-based approach to select pictures of the incoming video as key frames that are representative of a temporal region of the video which is visually homogeneous; a Content Analysis step, analysing the content of the key frames and classifying image patches of the key frames as interesting or not for the extraction of descriptors; a Descriptors Extracting step, extracting compact descriptors from the selected key frames, and defining a set of surrounding images also on the basis of input received from the Content Analysis step; a Temporal Coding step, multiplexing information about the time points at which said key frames have been extracted in the Key Frame Extracting step with the compact descriptors extracted in the Descriptors Extracting step, obtaining the descriptors.
