Dlib機器學習庫編譯以及安裝
阿新 • • 發佈：2019-01-29
這篇主要是編譯和安裝，最終目的是編譯出dilb.lib，這樣就可以將該靜態庫新增到我們自己的工程，供我們使用。
步驟一：下載Dlib庫
下載連結：http://dlib.net/
可以看到網站上還提供了了C++與Python的例程。
步驟二：用CMake製作dilb.lib
配置好路徑後，點選1，會提示你選擇編譯器，按照你的需求選擇就可以。前提是你的電腦必須安裝，比如你想編譯VS2013X64，你必須安裝VS2013.然後點選2.等待即可。
如果你以為這樣就OK，那就錯了，以上只是將Dlib轉換成了一個VS工程，我們還需要開啟VS，生成這個工程。
步驟三：生成dlib.lib
開啟F:/dlibbuild2013x64(這是我的儲存路勁，請換成你自己的)，找到Project.sln，開啟後
根據你的需要選擇Debug或Release，win32或X64
右擊ALL_BUILD->重新生成。等待編譯好後在F:/dlibbuild2013x64 裡多出兩個兩個資料夾Debug和x64，dlib.lib在Debug資料夾裡。匯入自己的工程就OK了！

Dlib庫的人臉檢測演算法使用的hog特徵與級聯分類器。廢話少說，下面開始。
步驟一：建立工程，配置工程。
建立工程就不多說了，不用預編譯頭，建立一個空專案就可以。下面主要說配置。
（1）
（2）
（3）就是把上一篇部落格中生成的dlib.lib匯入工程中
在此我使用的dlib庫提供的例子，我只是增加了中文註釋

This example program shows how <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">to</span> find frontal human faces <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">in</span> an image. In
particular, this program shows how you can take a list <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">of</span> images from the
command line <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">and</span> display each on the screen <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">with</span> red boxes overlaid on each
human face.
檢測正臉，可檢測一系列的圖片上的人臉並用紅色方框表示
The examples/faces folder contains some jpg images <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">of</span> people. You can run
this program on them <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">and</span> see the detections by executing the following command:
./face_detection_ex faces/*.jpg 可以使用此命令執行該程式
This face detector is made using the now classic Histogram <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">of</span> Oriented
Gradients (HOG) feature combined <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">with</span> a linear classifier, an image pyramid,
<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">and</span> sliding window detection scheme. This <span class="hljs-class" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">type</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">of</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">object</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">detector</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">is</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">fairly</span></span>
general <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">and</span> capable <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">of</span> detecting many types <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">of</span> semi-rigid objects <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">in</span>
addition <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">to</span> human faces. Therefore, <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">if</span> you are interested <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">in</span> making your
own object detectors <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">then</span> read the fhog_object_detector_ex.cpp example
program. It shows how <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">to</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">use</span> the machine learning tools which were used <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">to</span>
create dlib's face detector.
Finally, note that the face detector is fastest <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">when</span> compiled <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">with</span> at least
SSE2 instructions enabled. So <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">if</span> you are using a PC <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">with</span> an Intel <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">or</span> AMD
chip <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">then</span> you should enable at least SSE2 instructions. If you are using
cmake <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">to</span> compile this program you can enable them by using one <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">of</span> the
following commands <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">when</span> you create the build project:
cmake path_to_dlib_root/examples -DUSE_SSE2_INSTRUCTIONS=ON
cmake path_to_dlib_root/examples -DUSE_SSE4_INSTRUCTIONS=ON
cmake path_to_dlib_root/examples -DUSE_AVX_INSTRUCTIONS=ON
This will set the appropriate compiler options <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">for</span> GCC, clang, Visual
Studio, <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">or</span> the Intel compiler. If you are using another compiler <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">then</span> you
need <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">to</span> consult your compiler's manual <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">to</span> determine how <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">to</span> enable these
instructions. Note that AVX is the fastest but requires a CPU from at least
<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">2011.</span> SSE4 is the next fastest <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">and</span> is supported by most current machines.

/*確保檢測圖片是檢測器的兩倍。這第一點是十分有用的，因為臉部檢測器搜尋的人臉大小是<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">80</span>*<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">80</span>或者更大。

執行一次pyramid_up()我們能檢測<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">40</span>*<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">40</span>大小的了，如果我們想檢測更小的人臉，那還需要再次執行pyramid_up()函式。

（2）這個程式碼是帶參主函式，我們可以編譯完後用命令列的形式執行。如果你不想那麼麻煩，我們可以在屬性裡設定命令引數
做完這一切，編譯執行就可以了。
注意！！！
如果有如下報錯1>dlib.lib(base_widgets.obj) : error LNK2038: 檢測到“_ITERATOR_DEBUG_LEVEL”的不匹配項: 值“2”不匹配值“0”(dlib_face.obj 中)
1>dlib.lib(base_widgets.obj) : error LNK2038: 檢測到“RuntimeLibrary”的不匹配項: 值“MDd_DynamicDebug”不匹配值“MD_DynamicRelease”(dlib_face.obj 中)
原因是，你生成的dlib.lib是debug版本，而你的工程建立的是release版本，所有會有這個包括，只要將兩者保持一致，就沒有在這個報錯了！
