    鑒于這類系統在各大中小型企業的廣泛應用與相對滯后的研究水平,本文提出了三種新的能切實地解決目前尺寸鏈計算機輔助分析解算中在的各種難題的設計方案,第一種方案將尺寸鏈中各組成環能的極值組合起來,自動列方程組,求解每個組合情況下的封閉環尺寸,最後比較這些結果,得出封閉環的最大最小值;第二種方案將尺寸鏈各組成環向設定好的兩個方向投影,之後再分析各尺寸環投影分量的增減性,並且提供了組成環兩個方向上的投影分量增減性不一的復雜情況下的解決辦法,綜合組成環各投影分量的增減性,然後自動列出方程組,最後根據各組成環的投影分量以及所列的方程組來確定尺寸鏈封閉環的尺寸;第三種方案以蒙特卡洛法為原理,在尺寸鏈各組成環的值范圍內使用計算機產生大量隨機數,模擬實際大批量生產中的零件尺寸分佈情況,以更經濟更合理的方式分析、計算封閉環尺寸。
  2. Fractal coding has been proved useful for image compression. it is also proved effective for content - based image retrieval. in the paper, we present a block - constrained fractal coding scheme and a matching strategy for content - based image retrieval. in this coding scheme, an image is partitioned into non - overlap blocks of a size close to that of a query iconic image. fractal codes are generated for each block independently. in the similarity measure of fractal codes, an improved nona - tree decomposition scheme is adopted to avoid matching the fractal codes globally in order to reduce computational complexity. our experimental results show that our coding scheme and the matching strategy we adopted is useful for image retrieval, and is compared favorably with other two methods tested in terms of storage usage and computing time

    分形編碼在圖像壓縮方面得了很好的效果,同時,分形編碼也能夠用於基於內容的圖像檢索.本文提出了一種基於塊限制的分形編碼演算法和匹配策略,並將它們用於圖像檢索.在我們編碼演算法中,圖像會被分成互相不重疊的子圖像塊,然後對這些子圖像進行獨立地分形編碼,從而獲得整幅圖像的分形碼.該編碼演算法能夠在很大程度上減少編碼時間.在進行圖像間相似性的匹配時,我們採用改進的基於九叉樹的分配策略,從而避免全局地進行分形碼的匹配,減少了計算量.實驗結果說明,我們的編碼演算法和匹配策略能夠比較有效地應用於基於內容的圖像檢索,在計算時間和儲時間上都優于實驗中其它兩種方法
