Overview

libfacedetection

This is an open source library for CNN-based face detection in images. The CNN model has been converted to static variables in C source files. The source code does not depend on any other libraries. What you need is just a C++ compiler. You can compile the source code under Windows, Linux, ARM and any platform with a C++ compiler.

SIMD instructions are used to speed up the detection. You can enable AVX2 if you use Intel CPU or NEON for ARM.

The model files are provided in src/facedetectcnn-data.cpp (C++ arrays) & the model (ONNX) from OpenCV Zoo. You can try our scripts (C++ & Python) in opencv_dnn/ with the ONNX model. View the network architecture here.

examples/detect-image.cpp and examples/detect-camera.cpp show how to use the library.

The library was trained by libfacedetection.train.

How to use the code

You can copy the files in directory src/ into your project, and compile them as the other files in your project. The source code is written in standard C/C++. It should be compiled at any platform which supports C/C++.

Some tips:

Please add facedetection_export.h file in the position where you copy your facedetectcnn.h files, add #define FACEDETECTION_EXPORT to facedetection_export.h file. See: issues #222
Please add -O3 to turn on optimizations when you compile the source code using g++.
Please choose 'Maximize Speed/-O2' when you compile the source code using Microsoft Visual Studio.
You can enable OpenMP to speedup. But the best solution is to call the detection function in different threads.

You can also compile the source code to a static or dynamic library, and then use it in your project.

Performance far below result with Raspberry Pi 3 B+
于老师您好！

我在用Raspberry Pi 3 B+做调试，看到项目README的结论，这款设备在320x240的图片下，单核性能是8.1fps，多核性能是23.74fps。但是我这边在320x240的实际测试结果，多核只有4.2fps，远远低于前面给出的结论。方便的话，请帮我找找原因，谢谢！

运行速度比预期慢很多

于老师，您好！

我在windows系统运行图片人脸检测，912*524分辨率的png图片，可以正常完整运行，但是facedetect_cnn 这个函数耗时1903ms，我知道这是不合理的，但是我没有找到原因。电脑配置不差。使用默认的cmakeLists编译的facedetection_export.h，使用detect-image.cpp的示例代码做了一点修改，把图片地址写在代码里的。请问是会是什么原因导致？

Just ported to android and NOT run as fast as it told,can anyone figure out what is wrong with it?

I ported libfacedetection with jni and build with ndk19, then ran on a Nokia 7 plus android phone which cpu is Qualcomm 660. The face rect is given correctly but took almost 700ms to get the result without couting the convert time of bitmap to rgb. Barely can it run 2fps... And last time I check ,NEON was enabled. Can anyone help me with it ?

🔥🔥🔥 [Guide] How to use this lib in iOS

This lib is very useful! I try it in iOS and successful run.

download or clone this lib in your computer;
create New Xcode project;
add this lib's src to your project;
add the system lib libc++.tbd and other you need framework(eg. ACFoundation.framework etc.);
download opencv2.framework and add it in your project;
follow the example file to write the code.

!!!

modify facedetectcnn.h

//#define _ENABLE_AVX2 //Please enable it if X64 CPU
#define _ENABLE_NEON //Please enable it if ARM CPU

modify .m to .mm
import lib in your .mm

#import <opencv2/opencv.hpp>
#import <opencv2/imgcodecs/ios.h>
#import "ViewController.h"
#import "facedetectcnn.h"

you must import the opencv2/opencv.hpp first !!!

MyCode:

#import <opencv2/opencv.hpp>
#import <opencv2/imgcodecs/ios.h>
#import "ViewController.h"
#import "facedetectcnn.h"

//define the buffer size. Do not change the size!
#define DETECT_BUFFER_SIZE 0x20000
using namespace cv;

多线程调用

您好，11 月 10 日更新的这个版本您说的是可以在多线程调用，但是我用 VS2015（以及 opencv 3.1）测试发现，还是没法多线程同时调用啊，必须要加锁。另外，您提供的 dll 似乎是 VS2010 编译的，而新版的接口里面用到了 vector，编译器版本不匹配时在 vector 析构的时候就会出现问题，除非调用之前为 vector 预留足够的空间。

关于facedetect_cnn函数定义

我在facedetectcnn-model.cpp中找到了facedetect_cnn函数的定义，注释写着“input image, it must be RGB (three-channel) image!”而在头文件中facedetectcnn.h写着"input image, it must be BGR (three channels) insteed of RGB image!"。我觉得虽然是个小问题，但不一致的代码注释可能引起阅读混乱？

Is 150ms normal for AMD Ryzen 5 3550H in Single-thread？
I ran the detect-camera.cpp in example, and the average time consumption of face detection is 150ms. The environment is:

AMD Ryzen 5 3550H

16GB RAM

Microsoft Visual Studio 2022

By the way, I have enabled AVX2 and -O2 optimization when compling.

Problem about FDDB score

教授您好，有鉴于您的测试性能与精度相当地高，我使用您的模型测试FDDB的结果如下(红框部分)：

我想请问教授这个测试结果是正常的吗，我有看到有些评测说您的模型可达到 0.994 平均精度(AP)，但我的测试都只达到0.968左右，

我目前是个程式菜鸟，有些地方不太了解其中的意义，如果有什么地方有做错或少做的话请您给与指教，谢谢！

Upside-down images

Good morning. How can I implement processing of upside-down images? Looks like keypoints are the same, so I can't just check them and rotate image. Is there any tool or hint to work with that images?

Thank you.
