摘要:

纹理分析和分类一直是计算机视觉和模式识别领域面临的最大挑战之一。在这个问题上,Gabor小波已被证明是一个有用的技术来表征独特的纹理模式。然而,大多数用于提取Gabor幅度空间的描述符的方法通常不能充分地表示存在于唯一特征向量中的细节的丰富性。在本文中,我们提出了一种新的方法来增强的Gabor小波过程提取的幅度空间的分形签名。每个签名使用规范分析函数进行缩减,并连接以形成最终的特征向量。在多个纹理图像数据库上的实验证明了该方法的有效性。结果表明,该方法优于其他早期提出的方法,创建一个更可靠的技术纹理特征提取。

英文摘要:

Texture analysis and classification remain as one of the biggest challenges for the field of computer vision and pattern recognition. On this matter, Gabor wavelets has proven to be a useful technique to characterize distinctive texture patterns. However, most of the approaches used to extract descriptors of the Gabor magnitude space usually fail in representing adequately the richness of detail present into a unique feature vector. In this paper, we propose a new method to enhance the Gabor wavelets process extracting a fractal signature of the magnitude spaces. Each signature is reduced using a canonical analysis function and concatenated to form the final feature vector. Experiments were conducted on several texture image databases to prove the power and effectiveness of the proposed method. Results obtained shown that this method outperforms other early proposed method, creating a more reliable technique for texture feature extraction.
