Second , a limited rate algorithm for picture downsampling was improved , and the realization process was deduced in detail . the simulation results of different algorithms and theoretic deducing showed that this algorithm had relatively higher psnr and lower computation cost 接著,改進(jìn)了一種受限比例圖像下采樣算法,詳細(xì)推導(dǎo)了其實(shí)現(xiàn)過(guò)程,由不同算法的仿真結(jié)果和理論分析可知,該算法具有較高的信噪比和較低的運(yùn)算復(fù)雜度。
百科解釋
In signal processing, downsampling (or "subsampling") is the process of reducing the sampling rate of a signal. This is usually done to reduce the data rate or the size of the data.
