Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The part 1 appraises some of the principal Block Matching Algorithms (BMA) used in Video compression today. This work follows on from the work of Aroh Barjatya who implemented 7 common Block Search Algorithms to predict P-frames in MATLAB. Three further hybrid Diamond Search (DS) algorithms are implemented in MATLAB. Additional code is added to produce plots of the main metrics and to calculate some statistics such as Average Searching Points, Average PSNR (Peak Signal to Noise Ratio) and the Speed Improvement Ratio with respect to the DS and the Full Search (FS). Also, in part 1 the algorithm is called Hierarchical Adaptive Rood Pattern Search (HARPS) is proposed. This new algorithm includes the classic Adaptive Rood Pattern Search ARPS and hierarchical search MP (Hierarchical search or Mean pyramid). 56 pp. Englisch.…

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In part 2, fast motion estimation algorithm with name Fast Multigrid Pattern Search (FMPS) for H.264 is proposed. The proposed method showed that it works about 4 times faster. The peak signal to noise ratio in different video sequences shows better and worse results than characteristics of known algorithms (up to 3.75%) so it requires further investigation. Also, part 2 deals with the fast motion estimation algorithms for interframe encoding in the video data H.26 /HEVC standard. A new adaptive algorithm has been offered based on the analysis of the advantages and disadvantages of existing algorithms. The algorithm is called fast test zone search algorithm and includes the traditional test zone search algorithm (TZS) and the hierarchical search MP (Hierarchical Search or Mean Pyramid). The considered and proposed motion estimation algorithms have been tested in several video sequences using Microsoft Visual Studio software. The terms for algorithms evaluating were: the video sequence quality criterion (by PSNR), bitrate and encoding time. The proposed method showed that it works about 4 times faster. The average loss of the RD curve value (PSNR versus bitrate) is up to 4% in all. 52 pp. Englisch.…
