Coding of an arbitrarily shaped interlaced video in MPEG-4
نویسندگان
چکیده
The coding method in MPEG-4 for interlaced-video is introduced in this paper. Such a method is an extension of MPEG-2 interlaced coding tools to allow compression of arbitrarily-shaped interlaced-video. The new textureand-shape coding tools discussed here for arbitrarily-shaped interlaced-video provide good compression performance. It is demonstrated here that these interlaced tools improve the coding efficiency of MPEG-4 video in both subjective and objective means.

MPEG-4 standardized methods for the compression of arbitrarily shaped video objects
MPEG-4 is the most recent standard for audio-visual representation to be published by the International Organization for Standardization. One of the many new features of MPEG-4 is its ability to represent two-dimensional video objects of arbitrary shape. For this purpose, MPEG-4 uses the conventional motioncompensated discrete cosine transform syntax for color/texture coding and augments this w...
متن کاملFast Motion Estimation for Real-Time Shape-Adaptive MPEG-4 Video Encoding
This paper presents a fast motion estimator which can be used for real-time MPEG-4 encoding of arbitrarily shaped video objects. The approach is based on an existing algorithm which has already been applied successfully to format conversion. To exploit it for shape-adaptive coding, the algorithm has been adapted to the special properties of the MPEG-4 standard. With this new tool it becomes pos...
متن کاملMotion Re-estimation for MPEG-2 to MPEG-4 Simple Profile Transcoding
Since its emerging in mid 90’s, MPEG-2 [1] has been widely accepted by the digital video industry. There have been huge amount of video content stored in MPEG-2 format. MPEG4 [2] is the latest video coding standard out of MEPG targeted at network video applications. The Simple Profile (SP) of MPEG-4 is often used in practical applications. Thus, it is often necessary to perform MPEG-2 to MPEG-4...
متن کاملEfficient Encoding of Binary Shapes using MPEG-4
MPEG-4 Visual, that part of the upcoming MPEG-4 standard describing the coding of natural and synthetic video signals, allows the encoding of video objects using motion, texture and shape information. In this paper, the MPEG-4 context-based arithmetic encoder for encoding binary shape information is presented in the context of a new MPEG-4 video encoder architecture. The encoder architecture en...
متن کاملA New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks
The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...
