TLDR
This study gives objective and subjective quality assessment of decoded video frame by means of each search algorithm by giving a comparative study various search algorithms by Block Matching.Abstract:
The Block Matching is a temporal compression technique used in the video encoding. The main purpose of this method is to determine the displacements of each block of pixels between two successive frames. This technique, performed in the step of motion estimation, occupies the majority of the total time of video coding. The aim of this work is to give a comparative study various search algorithms by Block Matching. This study does not focus only on the complexity and computation time of each algorithm, but it also gives objective and subjective quality assessment of decoded video frame by means of each search algorithm.read more

Nonlocal Weighted Robust Principal Component Analysis for Seismic Noise Attenuation
TL;DR: A new denoising method based on the nonlocal weighted robust principal component analysis (RPCA) that adaptively sets weights with local noise variance and performs well also owing to the superiority of the iterative log-thresholding method.

Survey on Block Matching Algorithms for Motion Estimation
TL;DR: This paper has discussed the commonly used motion estimation algorithms such asFull Search (FS), Three-Step Search (TSS), New Three- step Search (NTSS%), Four-Step search (FSS), Diamond Search Algorithm (DS), and Hexagon Based Search Al algorithm (HEXBS) and analyzed these techniques by using Peak Signal to Noise Ratio (PSNR) values.

A survey on video compression fast block matching algorithms
Abir Hussain,Zaynab Ahmed +1 more
TL;DR: This paper focuses on a survey for two video compression techniques: the first is called the lossless block matching algorithm process, in which the computational time required to determine the matching macroblock of the Full Search is decreased while the resolution of the predicted frames is the same as for the Full search.
