Abstract:
The advances in multimedia technologies increased the interest in utilizing three dimensional (3D) video applications in mobile devices. However, wireless transmission is significantly prone to errors. Typically, packets may be corrupted or lost due to transmission errors, causing blocking artifacts. Furthermore, because of compression and coding, the error propagates through the sequence and salient features of the video cannot be recovered until a key-frame or synchronization-frame is correctly received. Without the use of concealment and enhancement techniques, visible artifacts would inevi

Abstract:
Two new algorithms are proposed for error concealment in the presence of cell/packet loss for packet video. Under packet switching network environments like Ethernet or ATM, some video packets may be lost or discarded due to transmission delay or channel congestion. Because video is normally compressed, small data losses may completely destroy the received video signal. Thus, lost block recovery or concealment becomes an essential issue for video communication over networks. The proposed algorithms use block DCT coding with one pixel overlap. Without any assumption on the smoothness of block b

Abstract:
Video coding standards such as H.264 AVC (Advanced Video Coding) rely on predictive coding to achieve high compression efficiency. Predictive coding consists of predicting each frame using preceding frames. However, predictive coding incurs a cost when transmitting over unreliable networks: frames are no longer independent and the loss of data in one frame may affect future frames. In this thesis, we study the effectiveness of Flexible Macroblock Ordering (FMO) in mitigating the effect of errors on the decoded video and propose solutions to improve the error concealment on H.264 decoders.

This thesis addresses the problem of cell loss when transmitting video data over an ATM network. Cell loss causes sections of an image to be lost or discarded in the interconnecting nodes between the transmitting and receiving locations. The method used to combat this problem is to use a technique called Error Concealment, where the lost sections of an image are replaced with approximations derived from the information in the surrounding areas to the error. This technique does not require any additional encoding, as used by Error Correction. Conventional techniques conceal from within the pixe

Multi-view video is capable of presenting a full and accurate depth perception of a scene. The concept of multi-view video is becoming more useful especially in 3D display systems by enhancing the viewing of high resolution stereoscopic images from arbitrary viewpoints without the use of any special glasses. Like monoscopic video, the multi-view video is faced with different challenges such as: reliable compression, storage and bandwidth due to the increased number of views as well as the high sensitivity to transmission errors.

碩士<br>國立中央大學<br>電機工程研究所<br>88<br>Error Detection and Concealment of Zerotree Wavelet Video Coding Abstract In the zerotree wavelet video coding system, there always exist direct correspondences between the coded symbols. Therefore, if one error occurs in the received bitstream, the rest of decoded data will lose their corresponding relationships and will not be able to reconstruct the original image. From this, we observe that the zerotree coding is very sensitive to transmission errors. In this thesis, we discuss how to improve the performance of the zerotree

The thesis includes three modification parts. First, the erroneous 1-to-1 pixels are concealed by the pixels from another view. The light differences between views are taken care by the information of motion vector of the projected coordination, and a reverse DIBR (Depth image based rendering) procedure. These procedures are based on assumptions that are better than the assumptions made in a state-of-the-art whole frame loss method fo

In previous research, system architecture is established by integrating a 3-D model-based coder and a 2-D video coder under very low bit-rate video coding. It makes the avatars to have more realistic expression as users’ representatives to form the video realistic avatars. In this thesis, we develop a new error concealment scheme for the 2-D video coder as the enhancement layer, which is expected to be more suitable in the

In this paper, an adaptive error concealment scheme is presented to recover corrupted macroblocks (MBs) in the H.264 video sequence. To increase the accuracy of the error concealment, the 4x4 partition mode is used to separate each MB into 16 4x4 subblocks. From motion vectors (MVs) of 4x4 subblocks in neighboring MBs, the proposed adaptive error concealment scheme classifies each corrupted MB into three types, namely the simple-type MB, the medium complexity-type MB, and the high complexit

Often even a slight error can make video unable to correctly decode. Therefore, there is a need for a good error control method to solve the problem. This paper presents a novel error detection and concealment strategy along with watermark technique. The proposed watermark-based scheme utilizes two kinds of watermark technique, a fragile watermark is used to detect and localize errors, and a robust watermark is used to reconstruct error a

Such loss further results in a serious error propagation problem especially when using motion compensated prediction processing. Therefore, many techniques have been developed to combat the effects of channel error on transmitted video. Even though a lot of techniques have been adopted, the residual transmission error may also exist. In this case, the error concealment methods will form “the last line of defense” for masking visual
