一种多特征融合的外观设计专利图像检索方法

摘要

提出一种多特征融合的外观设计专利图像检索方法.采用Hu不变矩和高斯描绘子两种算法描述图像形状特征;采用加权法融合形状特征和Gabor小波提取的纹理特征;用Adaboost算法进行相关性反馈.实验结果表明,提出的方法可以有效地实现外观设计专利图像的检索.%An image retrieval method for design patent is proposed based on multi-feature fusion.Invariant moments and Gaussian descriptor describe shape features of design patent images. Shape features and texture features obtained by using Gabor wavelet are integrated with a weighted method. Adaboost algorithm is employed for relevance feedback.The experimental results indicate that the proposed method is feasible for design patent image retrieval.
