基于lbp的特征提取，适合文理特征明显的图像，方便好用，有例子(Feature extraction based on lbp is suitable for images with obvious features of arts and sciences, which is convenient and easy to use.)

LBP（局部二值模式）是一种用来描述图像局部纹理特征的算子；它具有旋转不变性和灰度不变性等显著的优点。它是首先由T. Ojala, M.Pietik?inen, 和D. Harwood 在1994年提出，用于纹理特征提取。而且，提取的特征是图像的局部的纹理特征；(Local Binary Pattern describe the image local texture, invariant with the change of rota
