为了改善块拼接纹理合成图片在接缝处不平滑的现象，以及为了证明纹理传输约束的多样性，文中提出了一种改进的块拼接纹理合成技术，并把这种技术应用到了纹理传输中。文中对块拼接技术中最小切割路径的计算加入梯度结构信息，并且在选择匹配块时综合考虑重叠区域累计误差和最小切割路径，此外将改进的块拼接技术应用到纹理传输上，并对传输过程中依据的约束量的多样性进行探究。实验结果表明，改进的块拼接技术能够获得视觉上更好的合成结果，接缝处更加流畅连续，此外也验证了纹理传输中依据的两幅图像的对应约束量是多样的并不是单一的。
為瞭改善塊拼接紋理閤成圖片在接縫處不平滑的現象，以及為瞭證明紋理傳輸約束的多樣性，文中提齣瞭一種改進的塊拼接紋理閤成技術，併把這種技術應用到瞭紋理傳輸中。文中對塊拼接技術中最小切割路徑的計算加入梯度結構信息，併且在選擇匹配塊時綜閤攷慮重疊區域纍計誤差和最小切割路徑，此外將改進的塊拼接技術應用到紋理傳輸上，併對傳輸過程中依據的約束量的多樣性進行探究。實驗結果錶明，改進的塊拼接技術能夠穫得視覺上更好的閤成結果，接縫處更加流暢連續，此外也驗證瞭紋理傳輸中依據的兩幅圖像的對應約束量是多樣的併不是單一的。

In order to improve the phenomenon of image quilting texture synthesis results no smooth in seams and prove the diversity of constraint quantities in texture transfer,propose an improved technique of image quilting texture synthesis,and apply it into texture trans-fer. Add the calculation of minimum error boundary cut in the gradient structure information,and consider both sum of the square differ-ence and minimum error boundary cut when selecting matching patch. The improved technique is used to texture transfer,and probe the diversity of constraint quantities in texture transfer. The results show that the improved image quilting technique can obtain better synthesis results visually and seams are smoother. In addition,the results also prove the diversity of corresponding constraint quantities from two im-ages.
