Testing architecture for motion estimation in video coding systems

چکیده

Motion Estimation (ME) is the critical part of any video coding system. The video quality will be affected if an error has occurred in the ME. Motion Estimation is the process of determining the motion vectors that describe the transformation from one 2D image to other, usually from adjacent frames in a video sequence. In order to test Motion Estimation in a video coding system Error Detection and Correction Architecture (EDCA) is designed based on the Residue-and-Quotient (RQ) code. Multiple bit errors in the processing element (PE) i.e., key component of a ME, can be detected and the original data can be recovered effectively by using EDCA design. Experimental results indicate that the proposed design can detect multiple bit errors and effectively recover the data with reduced area and power. The area of the proposed architecture is reduced from 1152 to 114 and the power is reduced from 143.28mW to 59.39mW.

New 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...

Design and Implementation of Concurrent Error Detection and Data Recovery Architecture for Motion Estimation Testing Applications

BIST schemes generally focus on memory circuit; testing-related issues of video coding have seldom been addressed. Thus, exploring the feasibility of an embedded testing approach to detect errors and recover data of motion estimation (ME) is of worthwhile interest. Additionally, the reliability issue of numerous processing elements (PEs) in a ME can be improved by enhancing the capabilities of ...

روشی جدید برای اختفای خطا در فریم‌های ویدئو با استفاده از شبکه‌ عصبی RBF

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,...

An Improved Motion Vector Estimation Approach for Video Error Concealment Based on the Video Scene Analysis

In order to enhance the accuracy of the motion vector (MV) estimation and also reduce the error propagation issue during the estimation, in this paper, a new adaptive error concealment (EC) approach is proposed based on the information extracted from the video scene. In this regard, the motion information of the video scene around the degraded MB is first analyzed to estimate the motion type of...
