Key frame extraction methods aim to obtain a set of frames that can efficiently represent and summarize video contents and be reused in many video retrieval-related applications. An effective set of key frames, viewed as a high-quality summary of the video, should include the major objects and events of the video, and contain little redundancy and overlapped content. In this paper, a new key frame...
Based on the features of video content, this paper addresses the system of detecting pornographic videos. The system makes use of an improved algorithm for shot segmentation based on clustering and then extracts key frames. It converts the detection of video to identification of key frames. We use the skin color detection to detect the key frames which have been extracted. The experimental results...
Video key frame extraction is a type of video abstraction, which is one of the key problems in video content indexing and retrieval. Key frame extraction aims at finding a small collection of salient images extracted from a video sequence for visual content summarization. In this paper we propose a video key frame extraction method based on spatial-temporal color distribution. First we construct a...
