As a rapid growth of digital videos and data communications, video summarization that provides a shorter version of the video for fast video browsing and retrieval is necessary. Key frame extraction is one of the mechanisms to generate video summary. In general, the extracted key
A Semi-Automatic 2D-to-3D Video Conversion with Adaptive Key-Frame Selection
To compensate the deficit of 3D content, 2D to 3D video conversion (2D-to-3D) has recently attracted more attention from both industrial and academic communities. The semi-automatic 2D-to-3D conversion which estimates corresponding depth of non-key-frames through key-frames is mo
A novel video key-frame-extraction algorithm based on perceived motion energy model
The key frame is a simple yet effective form of summarizing a long video sequence. The number of key frames used to abstract a shot should be compliant to visual content complexity within the shot and the placement of key frames should represent most salient visual content. Motio
Within and Between Shot Information Utilisation in Video Key Frame Extraction
In consequence of the popularity of family video recorders and the surge of Web 2.0, increasing amounts of videos have made the management and integration of the information in videos an urgent and important issue in video retrieval. Key frames, as a high-quality summary of video
A neural network approach to key frame extraction
We present a neural network based approach to key frame extraction in the compressed domain. The proposed method is an amalgamation of both the MPEG-7 descriptors namely motion intensity descriptor and spatial activity descriptor. Shot boundary detection and block motion estimati
Video Shot Detection and Key Frame Extraction Using Faber Shauder DWT and SVD
Key frame extraction methods select the most representative frames of a video, which can be used in different areas of video processing such as video retrieval, video summary, and video indexing. In this paper we present a novel approach for extracting key frames from video seque
EMBEDDED KEY−FRAME EXTRACTION FOR CG ANIMATION BY FRAME DECIMATION (WedPmPO1)
This paper proposes a method for key−frame selec−tion of captured motion data. Motion capture systems have been widely used in CG amusement and human motion analysis such as games and athlete training. For manipulation, retrieval and transmission, the compact motion is often requ
Key Frame Extraction Based on Chaos Theory and Color Information for Video Summarization
Key frame based video summarization has emerged as an important task for efficient video data management. This paper proposes a novel technique for key frame extraction based on chaos theory and color information. By applying chaos theory, a large content change between frames be
Skeleton-based Adaptive In-between Generation for Hand-drawn Key Frames
For improving the efficiency of 2D animation production, this paper presents a method to create in-between frames based on hand-drawn key-frames. The outlines of characters or objects on two key-frames are used as inputs. First, a skeleton linkage of the target object is automati
Key-Frame Based Robust Video Hashing Using Isometric Feature Mapping
In order to identify videos on the Internet, a robust video hashing based on key frames and Isometric Feature Mapping (ISOMAP) is proposed in this paper. In this method, key frames extraction and hash generation are two major components. During the video hashing, key frame extrac
