摘　　要：在目前的纹理图像检索算法中,虽然提出了不少精度较高的算法,但是却很少考虑了运行效率的问题。利用小波函数对图像进行分解,再利用差分矩阵运算,在这个基础上,寻找优化的特征值进行提取,进行相似度度量。实验结果表明,分析方法不仅耗时比较短,而且有比较优越的检索性能。Although some algorithms in image texture retrieval have high precision, the procedure efficiency is ignored. Firstly the picture was discomposed by using wavelet transformation. Then difference matrix was used to operate. Based on it, the optimized character values were searched and distilled, and then likelihood measurement was carried out. The experiment demonstrates that this method has a shorter time consumption and a higher retrieval efficiency.
