The technical system evolves over time , which process parallels the micro - evolution of biological systems and illustrates the life cycle stages of child , growth , maturity and decline . what evolves is the characteristic index of the technical systems whose improvement is shown by a s - curve on the time - scale 技術(shù)系統(tǒng)處于不斷的進化過程中,其進化過程類似于生物的成長過程,要經(jīng)歷嬰兒期、成長期、成熟期和退出期四個階段,在時域上表現(xiàn)為特性參數(shù)沿s -曲線的增長。
It summarizes the basic conceptions of image compress processing , parallel processing technique and parallel algorithm briefly . then it emphasizes on the network parallel computing environment and logp model of parallel computation . this paper describes the methods of developing parallel algorithm and applications through the designing , analyzing , optimizing , and implementing of digital image processing parallel algorithm , include fft algorithm , wavelet transform , medium filtering , binary image algorithm etc 本文概述了并行處理技術(shù)和圖像壓縮技術(shù);并詳細闡述了并行算法及圖像處理算法的基本概念和模型;詳細討論了網(wǎng)絡(luò)并行l(wèi)ogp模型及并行算法的開發(fā)環(huán)境;并進行了fft并行編碼算法、小波并行編碼算法,中值濾波,圖像二值化等圖像處理的并行算法的設(shè)計與分析。
