接下来的部分将介绍根据查找表和FRC 在灰度和彩色模式下的操作。
The following sections describe the operation on the gray and color mode in terms of the lookup table and FRC .
局部二值模式(LBP)是一种灰度范围内的纹理描述方式。
Local Binary Patterns (LBP) is defined as a gray-scale invariant texture measure.
将这种滤波器放置在傅里叶反变换产生相关输出之前的联合功率谱面上，该技术可以应用在具有不同灰度图像的模式识别中。
The filter is put on the power spectrum before applying the inverse Fourier transform to yield the correlation output. This technique can be used in pattern recognition of grey level input image.
