【摘要】：針對(duì)影像數(shù)據(jù)分塊并行處理造成的接邊問題,該文基于構(gòu)建緩沖區(qū)的方法提出了一種新的拼接算法。該算法只在每一個(gè)數(shù)據(jù)分塊的右側(cè)和下側(cè)構(gòu)建緩沖區(qū),消除拼接線的原則是保證分割邊界的準(zhǔn)確性和拓?fù)潢P(guān)系的正確性。數(shù)據(jù)分塊完成后采用并行的策略對(duì)第一個(gè)塊進(jìn)行分割,然后將每一塊的分割結(jié)果與相鄰的塊進(jìn)行拼接,在緩沖區(qū)內(nèi)按一定規(guī)則判斷各塊分割對(duì)象是否保留并對(duì)拓?fù)潢P(guān)系進(jìn)行檢查,拼接完各塊后并行輸出對(duì)象矢量化后的結(jié)果。通過實(shí)驗(yàn)驗(yàn)證,該算法不僅保證了分割邊界的準(zhǔn)確性,而且能夠處理大影像,提高了工作效率。
[Abstract]:In order to solve the problem of edge joining caused by image data block parallel processing, this paper proposes a new stitching algorithm based on the method of constructing buffer. The algorithm only constructs buffers on the right and lower sides of each data block. The principle of eliminating the splicing lines is to ensure the accuracy of the segmentation boundary and the correctness of the topological relationship. After data partitioning is completed, the first block is segmented by a parallel strategy, and then the segmentation results of each block are spliced with adjacent blocks. According to certain rules in the buffer zone, the block partition object is determined whether to retain or not, and the topological relation is checked, and the result of the parallel output object vectorization is obtained after each block is stitched together. The experimental results show that the algorithm not only ensures the accuracy of the segmentation boundary, but also can process large images and improve the working efficiency.
