Abstract:
H.264/AVC (Advance Video Coding) standard developed by ITU-T Video Coding Experts Group(VCEG) and ISO/IEC JTC1 Moving Picture Experts Group (MPEG), is one of the most powerful andcommonly used format for video compression. It is mostly used in internet streaming sources i.e.from media servers to end users. This Master thesis aims at designing a CODEC targeting the Baseline profile on FPGA.Uncompressed raw data is fed into the encoder in units of macroblocks of 16×16 pixels. At thedecoder side the compressed bit stream is taken and the original frame is restored. Emphasis isput on the implement

Abstract:
Motion estimation and motion compensation comprise one of the most important compression methods for video communications. We propose a low-power design of a motion estimation block for a low bit-rate video codec standard H.263. Since the motion estimation is computationally intensive to result in large power consumption, a low-power design is essential for portable or mobile systems. Our block employs the Four-Step Search (4SS) method as its primary algorithm. The design and the algorithm have been optimized to provide adequate results for low-quality video at low-power consumption. The

Analysis of the Irish Republican Army (IRA) and their actions in the 1970s and 1980s offer insight into their use of just war theory in their conflict with the British government and ultra-loyalist Protestant forces in Northern Ireland. The historiography of Irish history is defined by its phases of nationalism, revisionism, and anti-revisionism that cloud the historical narrative of imperialism and insurgency in the North. Applying just war theory to this history offers a more nuanced understanding of the conflict of the Troubles and the I.R.A.’s usage of this framework in their ideology that

Abstract:
碩士<br>國立清華大學<br>資訊工程學系<br>90<br>Recently, many video encoding standards are applied to the communication devices. In most compression standards, such as H.263, H.26L, MPEG2 and MPEG4, motion estimation exploits large amount of computation power. An emerging video encoding technique, H.26L, achieves a bit rate reduction of about 30% with the same quality as in H.263 version 2. However, the encoding time is about three times longer because of complex operations. In this thesis, a new architecture for full-search variable-size block-matching motion estimation was proposed.

碩士<br>國立東華大學<br>電機工程學系<br>95<br>For the development of digital communication technology, data in transmission of compressed video over an error prone network, such as the Internet or wireless network, may lead to information loss due to the congestion or routing disruption. In this case, the loss frame is preferred to be recovered for meaningful application by the mechanism of error concealment in decoder. H.264/AVC is a newest video coding standard which provides approximately 50% bit rate saving for equivalent perceptual quality relative to the performance of prior standards. In this thesis,

The need of information hiding into digital multimedia attracted a great deal of interest for security and secret communication. Information hiding is a technique to hide secret messages into certain video sequence imperceptibly. The transmission of secret information in video conference is one of such applications.

In H.264, the computational complexity is linearly dependent on the number of allowed reference frames and block sizes using the full exhaustive search. Many fast block-matching algorithms reduce the computational complexity of motion estimation by carefully design the search patterns with different shapes or sizes which h

To use the architecture, each 16×16 marcoblock of the source frames should be partitioned into sixteen modules and one VBSME processor. Each module, realized by cascading 1D systolic arrays, is responsible for the block-matching operations of a different primitive subblock. The realization has the advantages of high throughput, high flexi

To achieve the highest coding efficiency, H.264 adopts complicated coding schemes, employing motion compensation with variable blocks sizes from 16x16 to 4x4, multiple reference frames for temporal prediction, quarter-pel motion vector a

However it will cause visible distortion when video is decoded from inverse quantization process, particularly for blocky effect. In order to remove the blocky on image, we propose an efficient filtering algorithm which can improve the performance of H.264/AVC adaptive deblocking filter. The proposed manner is to adjust two parameters of deblocking filter. The parameter values can be auto-adjusted based on image features for b

It can achieve better motion-compensation with variable block size coding from 4×4 to 16×16. However, the complexity is high since there are 41 motion vectors to be computed for one MB block. First, we propose a fast algorithm that consists of fast 9-Postion ME and mode decision algorithm with dynamic thresholds to reduce the complexity of motion estimation (ME) for various coding modes.
