fine directional interpolation for spatial error concealment Mccleary, Washington

Unfortunately, they may unavoidably cause severe distortion if adopted neighboring macroblock is drastically damaged as well and perform poor in preserving edges. "[Show abstract] [Hide abstract] ABSTRACT: In this paper, we This loss affects the original video and it occur some error. Although carefully collected, accuracy cannot be guaranteed. Error concealment methods include frequency domain error concealment, temporal error concealment and spatial error concealment [3, 4] .

Computer storage and transmission systems use a number of measures to provide data integrity, or lack of errors. A novel objective function called minimum entropy of bad prediction (MEBP) is proposed. It is often required to interpolate (i.e. As effects of errors in estimating the missing DC values will appear as a number of stripes across the image, a technique for removing such stripes is also developed.

of ECE, Hanyang Univ., Seoul Jechang Jeong Dept. For a video sequence, we exploit its inherent temporal-spatially correlated property, i.e., temporal continuity and spatial smoothness, from a global view point. LCD pixels are manufactured in a two-dimensional grid, and are often represented using dots or squares, but CRT pixels correspond to their timing mechanisms and sweep rates. Assignment does not change access privileges to resource content.

Pairwise image registration is inappropriate due to the lack of consideration of global coherence.

However, the images in the raw image sequence are not aligned with each other and therefore must be spatially registered. Examples of such channels are copper wires, optical fibres, wireless communication channels, and storage media.

This approach improves the capability to more reliably recover high-detailed contents in the corrupted block.

MEBP is based on information theory and can be used for multi-modal image registration as well as image sequence alignment (ISA).

This dissertation describes several new methods employed by the atlas construction process. The proposed scheme is based on fuzzy logic reasoning and can be divided into three main steps: (1) hierarchical compass interpolation/extrapolation (HCIE) in the spatial domain for initial recovery of lost Characteristic of the results are those of the "Lena" JPEG image when one fourth of periodically spaced blocks in the image have errors. Experiments show that the proposed concealment scheme can restrain the diffusion of erroneous macro block and improve the quality of the rebuilt frame subjectively as well as objectively.Article · Jun 2011

In the second stage, the data of missing blocks is reconstructed by exploiting the correlation between adjacent blocks. Interpolations are performed on a local pel neighborhood along the directions specified by the edge classifier.
