Noise-robust recursive motion estimation for H.263-based videoconferencing systems
نویسندگان
چکیده
The key element in realizing low cost real{time software implementations of a H.263 videoconferencing system is a fast motion estimation algorithm, which only slightly decreases coding e ciency. We propose a spatio{temporal recursive estimator that combines an excellent coding e ciency with a high computational e ciency. Experimentally, the new algorithm proves to be comparable to full{search block matching when encoding typical videoconferencing sequences in presence of additive noise, even though the computational burden has been greatly reduced.

Robust Video Coding Based on Tree Structure Motion Compensation
One inherent problem of network video is the sensitivity of the compressed bit-stream to data loss. Error propagation is one of the most important factors that affect the quality of network video. This paper discusses a new scheme for robust video coding to cope with this problem. First, error propagation in Block Motion Compensation (BMC) in H.263 is analyzed using a Markov chain model. Severa...
متن کاملNew adaptive interpolation schemes for efficient meshbased motion estimation
Motion estimation and compensation is an essential part of existing video coding systems. The mesh-based motion estimation (MME) produces smoother motion field, better subjective quality (free from blocking artifacts), and higher peak signal-to-noise ratio (PSNR) in many cases, especially at low bitrate video communications, compared to the conventional block matching algorithm (BMA). Howev...
متن کاملRobust Reweighted MAP Motion Estimation
This paper proposes a motion estimation algorithm that is robust to motion discontinuity and noise. The proposed algorithm is constructed by embedding the least median squares (LMedS) of robust statistics into the maximum a posteriori (MAP) estimator. Difficulties in accurate estimation of the motion field arise from the smoothness constraint and the sensitivity to noise. To cope robustly with ...
متن کاملGlobal motion estimation and robust regression for video coding
In the H.263 Version 2 (H.263+) coding standard, the global motion compensation can be introduced by using Reference Picture Resampling (Annex. P) syntax. Such an application requires that the global motion parameters be estimated automatically. In this paper, we propose a global motion estimation algorithm based on the Taylor Expansion Equation and robust regression technique using probabilist...
متن کاملM 4 S a Model - Based Pel - Recursive Motion Estimation Algorithm
In this paper, a model-based approach to pel-recursive motion estimation is presented. The derivation of the algorithm is similar to the Wiener-based pel-recursive motion estimation algorithm. However, the proposed algorithm utilizes the spatiotemporal correlations in an image sequence by considering an autoregressive model for the motion compensated frames. Therefore, depending on the support ...
