Segmentation-Based Motion Estimation and Residual Coding for Packet Video
نویسنده
چکیده
Image transmission via packet switched networks has a significant impact on encoded image data. To develop an efficient image codec for packet video, the goals of image coding are redefined and formulated as an optimization problem. Guided by these goals, a set of design requirements and a new segmentation based coding technique is developed. This approach features region based motion estimation, region based residual coding and region based single frame coding. The performance of the proposed algorithm is evaluated anl a packet loss compensation algorithm is presented. As a result, good image quality at very low-bit rates can be achieved.

Traffic Scene Analysis using Hierarchical Sparse Topical Coding
Analyzing motion patterns in traffic videos can be exploited directly to generate high-level descriptions of the video contents. Such descriptions may further be employed in different traffic applications such as traffic phase detection and abnormal event detection. One of the most recent and successful unsupervised methods for complex traffic scene analysis is based on topic models. In this pa...
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...

Transmission of compressed video over error prone channels may result in packet losses, which can degrade the image quality. Error concealment (EC) is an effective approach to reduce the degradation caused by the missed information. The conventional temporal EC techniques are always inefficient when the motions of the video object are irregular. In this paper, in order to overcome this problem,...

متن کاملOn motion modeling and estimation for very low bit rate video coding
In video coding at high compression rates, e.g., in very low bit rate coding, every transmitted bit carries a signii-cant amount of information that is related either to motion parameters or to intensity residual. As demonstrated in the SIM-3 coding scheme, a more precise motion model leads to improved quality of coded images when compared with the H.261 coding standard. In this paper, we prese...
