gabor提取纹理特征，k-means方法无监督聚类进行图像分割,extract texture feature, cluster by k-means

图像检索中的纹理特征；基于共生矩阵纹理特征提取，根据输入图像数据进行计算并返回八维纹理特征行向量-Texture feature in image retri texture feature extraction based on co-occurrence matrix, and then calculate and return eight dimensional texture feature row vector according to the input image data.
