Similar Image Retrieval using affine invariant wavelet

基于内容的图像检索为从大型图像数据库中检索图像提供了方便的途径，因而得到了广泛的研究。本文提出了一种基于区域的图像检索方法，该方法利用小波变换系数计算得到的纹理特征进行图像分割和索引，在纹理特征提取和图像分层分割方面优于基于小波变换的区域检索方法。

Content-based image retrieval, which provides convenient ways to retrieve images from large image databases, has been studied actively. While many previous image retrieval techniques do not look at regions in an image, region based image retrieval techniques have been gaining attention recently.We propose a region-based image retrieval method which performs image segmentation and indexing using texture features computed from wavelet coefficients.The proposed method has advantages in texture feature extraction and hierarchical image segmentation over the previous region-based techniques using wavelet transform.
