如何使用OpenCV计算局部二值模式直方图? [英] How to calculate Local Binary Pattern Histograms with OpenCV?

问题描述

我已经看到OpenCV提供了基于LBP的分类器

I have already seen that OpenCV provides a classifier based on LBP histograms:

但是我想访问LBP直方图本身.例如:

But I want to have access to the LBP histogram itself. For instance:

histogram = calculate_LBP_Histogram( image )

在OpenCV中有执行此功能的功能吗?

Is there any function that performs this in OpenCV?

推荐答案

您可以在此处获得使用OpenCV的Mat数据结构来计算LBP的C ++代码:

You can get the C++ code for computing LBP using OpenCV's Mat data structure here:

http://www.bytefish.de/blog/local_binary_patterns

您应该也可以在同一站点上找到Python版本.

You should be able to find the Python version as well on the same site.

该代码是由Philipp Wagner编写的，我相信他曾将您提到的人脸识别代码贡献给OpenCV，所以应该是同一回事.

The code is written by Philipp Wagner, who I believe contributed the face recognition code you mentioned to OpenCV, so it should be the same thing.

在文件OpenCV-2.4.2/modules/contrib/src/facerec.cpp中找到LBP代码作为静态函数.不幸的是，它似乎没有公开供公众使用(至少对于OpenCV 2.4.2).

The LBP code is found in the file: OpenCV-2.4.2/modules/contrib/src/facerec.cpp as a static function. Unfortunately, it does not appear to be exposed for public use (at least for OpenCV 2.4.2).
