We present a method for automatic textual annotation of compressed video. Initially, cuts are detected in the video sequence where consecutive frames show a large difference. Key frames are then extracted to represent each shot. A video sequence is, thus, condensed into a few images, hence this forms a compact key frame representation of the video. Each key frame is compared with an annotated d...

This article topics based on multi-feature fusion the Mean shift target tracking technology belongs to the field of intelligent video analysis, moving target tracking is interested in moving target location each image in a video sequence to find and acquire the target movement. Moving target tracking problem can be stated as interested in moving target movement prediction in the video sequence,...

Development of various multimedia applications hinges on the availability of fast and eecient storage, browsing , indexing, and retrieval techniques. Given that video is typically stored eeciently in a compressed format, if we can analyze the compressed representation directly, we can avoid the costly overhead of decompressing and operating at the pixel level. Compressed domain parsing of video...

This paper presents a steganography method using lossy compressed video which provides a natural way to send a large amount of secret data. The proposed method is based on 3-D set partitioning in hierarchical trees (SPIHT) algorithm for video compression and bit-plane complexity segmentation (BPCS) steganography. In 3-D SPIHT coding, wavelet coefficients in 3-D discrete wavelet transformed vide...

A new low complexity approach to motion estimation for video indexing is proposed in this paper. The fast polynomial regression transform (FPRT) is utilized to provide the e cient storage layout model and e ective video database for manipulating the multimedia information system. The video content information of video image is compressed by FPRT. Global Translational motion vectors and location...

ATM networks will carry a wide variety of data over the same packet switching network. A majority of this traac is expected to be real-time video generated by video on demand, video conferencing systems, etc. We study the characteristics of video data compressed using standard coding algorithms namely, JPEG, MPEG and also popular ones such as the video conferencing software NV. A wide range of ...
