摘要
将小波变换的多尺度技术应用到图像检索中的形状特征的边缘检测 ,利用不变矩的仿射不变性进行形状特征提取 ,并以图像特征向量的欧氏距离进行图像的相似度匹配。试验结果表明 ,使用该算法可以提高基于内容的图像检索的准确率与检索速度。
In this paper, the multiscale technique of wavelet transform is used in image edge detection. Affine immutability of invariant moment is used in the feature extraction of the shape and the Euclidian Distance of image eigenvector is used in image similarity match. Experimental results indicate that the performance of CBIR can be effectively improved.
