裸机Ubuntu16.04配置Dlib19.4 (Python人脸检测例子)
来源:互联网 发布:iphone软件排行 编辑:程序博客网 时间:2024/05/19 12:39
Windows版本Dlib配置链接: 地址
1.准备工作
Dlib库下载链接: 地址
首先需要Cmake以及编译C++成python程序的工具【参考1】
sudo apt-get install libboost-python-dev cmake
如果没有setuptools工具的需要安装,指令如下:
python2.x:
wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
python3.x
wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python3.4
2.安装dlib
接着cd到Dlib的目录运行,参考:地址
运行:(如果提示没权限记得 sudo su)
python setup.py install
3.测试
pythonimport dlib无任何异常说明安装成功~
4.运行人脸检测
下面来运行经典的Dlib的landmark~
先安装下pip,参考链接:地址
sudo apt-get install python-pip python-dev build-essential sudo pip install --upgrade pip sudo pip install --upgrade virtualenv
然后安装skimage.io模块,参考:地址
sudo pip install scikit-image或者
sudo apt-get install python-skimage
人脸检测
新建fr.py
#!/usr/bin/python# The contents of this file are in the public domain. See LICENSE_FOR_EXAMPLE_PROGRAMS.txt## This example program shows how to find frontal human faces in an image. In# particular, it shows how you can take a list of images from the command# line and display each on the screen with red boxes overlaid on each human# face.## The examples/faces folder contains some jpg images of people. You can run# this program on them and see the detections by executing the# following command:# ./face_detector.py ../examples/faces/*.jpg## This face detector is made using the now classic Histogram of Oriented# Gradients (HOG) feature combined with a linear classifier, an image# pyramid, and sliding window detection scheme. This type of object detector# is fairly general and capable of detecting many types of semi-rigid objects# in addition to human faces. Therefore, if you are interested in making# your own object detectors then read the train_object_detector.py example# program. ### COMPILING/INSTALLING THE DLIB PYTHON INTERFACE# You can install dlib using the command:# pip install dlib## Alternatively, if you want to compile dlib yourself then go into the dlib# root folder and run:# python setup.py install# or# python setup.py install --yes USE_AVX_INSTRUCTIONS# if you have a CPU that supports AVX instructions, since this makes some# things run faster. ## Compiling dlib should work on any operating system so long as you have# CMake and boost-python installed. On Ubuntu, this can be done easily by# running the command:# sudo apt-get install libboost-python-dev cmake## Also note that this example requires scikit-image which can be installed# via the command:# pip install scikit-image# Or downloaded from http://scikit-image.org/download.html. import sysimport dlibfrom skimage import iodetector = dlib.get_frontal_face_detector()win = dlib.image_window()for f in sys.argv[1:]: print("Processing file: {}".format(f)) img = io.imread(f) # The 1 in the second argument indicates that we should upsample the image # 1 time. This will make everything bigger and allow us to detect more # faces. dets = detector(img, 1) print("Number of faces detected: {}".format(len(dets))) for i, d in enumerate(dets): print("Detection {}: Left: {} Top: {} Right: {} Bottom: {}".format( i, d.left(), d.top(), d.right(), d.bottom())) win.clear_overlay() win.set_image(img) win.add_overlay(dets) dlib.hit_enter_to_continue()# Finally, if you really want to you can ask the detector to tell you the score# for each detection. The score is bigger for more confident detections.# The third argument to run is an optional adjustment to the detection threshold,# where a negative value will return more detections and a positive value fewer.# Also, the idx tells you which of the face sub-detectors matched. This can be# used to broadly identify faces in different orientations.if (len(sys.argv[1:]) > 0): img = io.imread(sys.argv[1]) dets, scores, idx = detector.run(img, 1, -1) for i, d in enumerate(dets): print("Detection {}, score: {}, face_type:{}".format( d, scores[i], idx[i]))
运行:
python fr.py 1.jpeg
效果如图:
之后再写一篇landmark的……
