Robust Scene Recognition Using Scene Context Information for Video Contents
نویسندگان
چکیده
We propose a robust scene recognition framework using scene context information for multimedia contents. In multimedia contents, some scene sequences are more likely to happen compared with other scene sequences. We employ a statistical approach to deal with this scene context information. We employ a hidden Markov model (HMM) to model each scene and an n-gram language model to represent the scene context. We evaluated the proposed method in scene recognition experiments for 16 scenes in video data of 25 baseball games. The proposed method significantly improved the results compared to that without scene context information.

An Improved Motion Vector Estimation Approach for Video Error Concealment Based on the Video Scene Analysis
In order to enhance the accuracy of the motion vector (MV) estimation and also reduce the error propagation issue during the estimation, in this paper, a new adaptive error concealment (EC) approach is proposed based on the information extracted from the video scene. In this regard, the motion information of the video scene around the degraded MB is first analyzed to estimate the motion type of...

Analyzing motion patterns in traffic videos can be exploited directly to generate high-level descriptions of the video contents. Such descriptions may further be employed in different traffic applications such as traffic phase detection and abnormal event detection. One of the most recent and successful unsupervised methods for complex traffic scene analysis is based on topic models. In this pa...

Scene change detection plays an important role in a number of video applications, including video indexing, searching, browsing, semantic features extraction, and, in general, pre-processing and post-processing operations. Several scene change detection methods have been proposed in different coding standards. Most of them use fixed thresholds for the similarity metrics to determine if there wa...
متن کاملRecognition of Characters from Streaming Videos
Over the past few years, Video has become one of the prime source for recreation, be it Television or Internet. Television brings a whole lot of professionally produced video content (International or local, sports or educational, news or entertainment) to the home for the masses. Similarly, Internet hosts a whole lot of video content uploaded by other users. Understanding the context of the vi...
متن کاملSCENE BY SCENE SCRIPT GENERATION FOR LIVE ACTION HOLLYWOOD MOVIES by CHRISTIAN DECKER Advisor
Today there is no “Google for video” that actually searches the content of the video. Content-based video search can be achieved by indexing video scene transcriptions much like a film script. We propose to develop a tool that automatically processes video and produces a transcript representing its contents. This processing step may involve scene segmentation, object recognition, behavior recog...
