In this paper, a new PCA based method for video compression is introduced. This method extracts the features of video frames and process them adaptively based on required accuracy. This idea improves the quality of compression effectively. In this paper, we focused on the fact that video is a composition of sequential and correlated frames, so we can apply the PCA to these high correlated frame...

Video Compression has played an important role in Multimedia data storage and transmission. Video compression techniques removes spatial as well as temporal redundancy using intra-frame and inter-frame coding respectively. A large level of compression can be achieved through inter-frame coding. In this paper, three step search with track knowledge has been analyzed by comparing its performance ...

In video processing, energy efficient real time video compression and transmission finds numerous applications. In this paper entropy coding is performed for video compression based on three‐dimensional discrete wavelet transform. Currently the most popular video coding approach is an extension of H.264/SVC standard. It provides high compression efficiency due to motion compensation and inter‐l...

One of the top tasks for video streaming, video surveillance, video conferencing and video broadcasting is a low bit rate and real-time video coding. The most popular low bit rate video compression approach is based on the H.264/AVC standard [1]. This standard provides high compression efficiency due to hybrid video coding which includes intra-frame prediction, variable-size block motion estima...

This paper proposes a robust watermarking method for uncompressed video data against H.264/AVC and H.265/HEVC compression standards. We embed the watermark data in the midrange transform coefficients of a block that is less similar to its corresponding block in the previous and next frames. This idea makes the watermark robust against the compression standards that use the inter prediction tech...

Many advanced video applications require manipulations of compressed video signals. Popular video manipulation functions include overlap (opaque or semitransparent), translation, scaling, linear filtering, rotation, and pixel multiplication. In this paper, we propose algorithms to manipulate compressed video in the compressed domain. Specifically, we focus on compression algorithms using the di...

MPEG-4 is a method of defining compression of audio and video digital data. MPEG-4 videos double compression method is used to decompress video from spatial domain to the frequency domain and then resaved with a different quantization matrix. Markov feature is a second order statistics which was adopted to detect double compression artifacts in the original video. In proposed system, double com...

This paper discusses the current state of compression for digital video on the desktop. Today there are many choices for video compression that yield different performance in terms of compression factor, quality, bitrate, and cost. Users want a single low cost solution which, unfortunately, today is non-existent. Consequently, users will have to develop applications in an environment with multi...
