Video error concealment is an error hiding Technique. Recently there is need of Error Concealment in video applications. Video applications are widely used in many domains such internet videos, entertainment media such as TV and DVD, video conferencing, video surveillance etc. In this paper, Video Error Concealment is achieved by Moment Invariance using MATLAB. Error is detected using moment invariance and corrected by using block matching algorithm. In Moment Invariance method, error frame is divided into macroblocks of size 16∗16 and that is compared with the macro block of previous frame. Moment invariance algorithm is carried out in three steps. The first step is designation of candidate motion vector set. The second step is to adaptively determine the error in the current and reference frame for feature extraction. The last step is to find the error function calculation using Moment Invariance. The quality of the video is analyzed using Structural Similarity Index (SSIM) and Peak Signal to Noise Ratio (PSNR). Result indicates that quality is improved for different error videos. © 2017 IEEE.
