Texture Image Retrieval by Multi-directional Information Fusion of Wavelet Domain

JIANG Lin1,2,FANG Bin1,TANG Yuan-yan1,XU Da-yuan1(1.College of Computer Science,Chongqing University,Chongqing 400030;2.Training Base of Guizhou Division of Armed Police,Guiyang 550005)  
Texture retrieval with Dual-Tree Complex Wavelet Transform(DTCWT) is effective to improve performance relative to conventional wavelet transform due to its multi-directional information.The conventional wavelet transform gives different directional information from DTCWT.Aiming at this problem,this paper proposes a texture image retrieval approach combining the DTCWT and the conventional wavelet transform to extract features.Experimental results on Brodatz database show that the proposed method has better performance than the DTCWT and the traditional wavelet transform.
