In this paper , two important modifications in dct - based coding algorithm are suggested after making deep study on the generally used scheme of h . 263 coder . first , we find plenty of invalid computation in the transformation part of the h . 263 coder and an improved scheme based on the pre - transform decision to avoid invalid computation is proposed . second , in the motion estimation part of the coder , we find that normal search algorithms are not effective , which neglects different levels of motion in image sequences , and we suggest a new search algorithm which has variable search region based on the difference of motion level . combining the pre - transform decision scheme with variable search region method in motion estimation , a global decision coding scheme is provided , which greatly increases the coding speed of h . 263 coder 本文對h . 263編碼算法的現有實現方法作了深入的分析,首先發現變換部分存在大量無效運算,提出了在變換前加判決的前變換判決的編碼方案,以壓縮無效的變換運算;其次發現運動估計部分由于忽略了圖像場景的分級運動而存在一定的無效搜索運算,提出了基于分級運動的可變搜索域法來壓縮無效的搜索運算;最后將前變換判決方案與運動估計的可變搜索域法有機地結合在一起,提出了全局判決編碼方案,從而比較全面地改進了現有實現方法,因而能大幅度地提高編碼器的編碼速度
Abstract : according to time - sharing price counting policy of electricpower , the relationships of current density and current efficiency at different ratios of sulfuric acid and zinc are obtained through analyzing process data of electrolytic zinc process ( ezp ) , and an optimization model of time - sharing power supply dispatching system ( tpsds ) of ezp is established . an single - loop simulated anneling algorithm with mutation and variable searching spaces is proposed and applied to the tpsds to obtain optimal time - sharing power supply scheme . industrial practical results show that the optimal dispatching system can greatly decrease the power consumption of ezp and increase the time - sharing profits 文摘:依據電力部門的分時計價政策,根據由生產過程數據所建立的不同酸鋅比下電流密度與電流效率間關系,建立鋅電解過程分時供電優化模型.同時,提出一種帶變異操作和變搜索空間的單循環模擬退火算法,并將該算法應用于分時供電優化調度,獲得最優的分時供電方案.工廠運行結果表明:整個優化調度系統能顯著降低鋅電解過程的電耗并增加分時效益
