《PHP實(shí)戰(zhàn)：MacOS 安裝 PHP的圖片裁剪擴(kuò)展Tclip》要點(diǎn)：
本文介紹了PHP實(shí)戰(zhàn)：MacOS 安裝 PHP的圖片裁剪擴(kuò)展Tclip，希望對(duì)您有用。如果有疑問(wèn)，可以聯(lián)系我們。
Tclip 用于圖片裁剪,有以下特點(diǎn)：PHP實(shí)戰(zhàn)
能進(jìn)行人臉識(shí)別.圖片中有人臉,將自動(dòng)視為人臉區(qū)域?yàn)橹匾獏^(qū)域,將不會(huì)被裁剪掉.
自動(dòng)識(shí)別其它重要區(qū)域.如果圖片中未識(shí)別出人臉,則會(huì)根據(jù)特征分布計(jì)算出重區(qū)域.
總而言之,自動(dòng)識(shí)別圖片中的重要區(qū)域,并且在圖片裁剪時(shí)保存重要區(qū)域.

安裝opencvPHP實(shí)戰(zhàn)
根據(jù)github上的闡明,在CentOS上安裝沒(méi)有問(wèn)題,但在我的MacOS上就掛了.PHP實(shí)戰(zhàn)
首先遇到的問(wèn)題便是,opencv安裝不過(guò)去.還好,上github下載最新的opencv-2.4.11 安裝成功.PHP實(shí)戰(zhàn)

使用當(dāng)前最新版本 OpenCV 2.4.11PHP實(shí)戰(zhàn)
安裝依賴PHP實(shí)戰(zhàn)
在安裝opencv之前,先安裝一些依賴包：PHP實(shí)戰(zhàn)
代碼如下:
brew install gtk+? pkgconfig libpng zlib libjpeg libtiff cmake
提示： brew的安裝使用請(qǐng)參考 http://brew.sh/PHP實(shí)戰(zhàn)
安裝opencvPHP實(shí)戰(zhàn)
開(kāi)始安裝 opencv：PHP實(shí)戰(zhàn)
代碼如下:
tar zxf opencv-2.4.11.tar.gz
cd opencv-2.4.11
cmake CMakeLists.txt
make && make install
安裝php tclipPHP實(shí)戰(zhàn)
先下載：https://github.com/exinnet/tclip/archive/master.zipPHP實(shí)戰(zhàn)
然后繼續(xù)：PHP實(shí)戰(zhàn)
代碼如下:
unzip tclip-master.zip
cd tclip-master/php_ext
phpize
./configure
如果不出不測(cè),到這一步,應(yīng)該就掛掉了,提示：PHP實(shí)戰(zhàn)
代碼如下:
checking for opencv.pc file in default path... found in /usr/lib/pkgconfig
found in /usr/local/lib/pkgconfig
configure: error: no result from pkg-config opencv --libs --cflags opencv
在 Tclip 作者的頁(yè)面上 http://www.bo56.com/tclip%E4%BA%BA%E8%84%B8%E8%AF%86%E5%88%AB%E5%9B%BE%E7%89%87%E8%A3%81%E5%89%AA/#downloadPHP實(shí)戰(zhàn)
評(píng)論中,也有網(wǎng)友遇到了類似的問(wèn)題,提出修改方法為：PHP實(shí)戰(zhàn)
將 config.m4 中的 判斷語(yǔ)句test ${i:${#i}-3} = “.so”,改為 test ${i:${#i}-6} = ".dylib”,并嘗試將46行的.so 也改稱 .dylib
依然提示no result的差錯(cuò)～PHP實(shí)戰(zhàn)
再翻翻config.m4的代碼和執(zhí)行 pkg-config opencv --libs --cflags opencv的輸出成果：PHP實(shí)戰(zhàn)
代碼如下:
-I/usr/local/include/opencv -I/usr/local/include -L/usr/local/lib -lopencv_calib3d -lopencv_contrib -lopencv_core -lopencv_features2d -lopencv_flann -lopencv_gpu -lopencv_highgui -lopencv_imgproc -lopencv_legacy -lopencv_ml -lopencv_nonfree -lopencv_objdetect -lopencv_ocl -lopencv_photo -lopencv_stitching -lopencv_superres -lopencv_ts -lopencv_video -lopencv_videostab
感覺(jué)怎么對(duì)不上,于是跑到Linux安裝勝利的服務(wù)器執(zhí)行了一下,輸出結(jié)果如下：PHP實(shí)戰(zhàn)
代碼如下:
-I/usr/local/include/opencv -I/usr/local/include /usr/local/lib/libopencv_calib3d.so /usr/local/lib/libopencv_contrib.so /usr/local/lib/libopencv_core.so /usr/local/lib/libopencv_features2d.so /usr/local/lib/libopencv_flann.so /usr/local/lib/libopencv_gpu.so /usr/local/lib/libopencv_highgui.so /usr/local/lib/libopencv_imgproc.so /usr/local/lib/libopencv_legacy.so /usr/local/lib/libopencv_ml.so /usr/local/lib/libopencv_nonfree.so /usr/local/lib/libopencv_objdetect.so /usr/local/lib/libopencv_photo.so /usr/local/lib/libopencv_stitching.so /usr/local/lib/libopencv_ts.so /usr/local/lib/libopencv_video.so /usr/local/lib/libopencv_videostab.so
再看他的斷定代碼：PHP實(shí)戰(zhàn)
代碼如下:
OPENCV_FLAGS="`pkg-config opencv --libs --cflags opencv`"
for i in $OPENCV_FLAGS;do
if test ${i:0:2} = "-I" ;then
PHP_ADD_INCLUDE(${i:2})
elif test ${i:${#i}-3} = ".so" ;then
dir_name=`dirname $i`
file_name=${i/$dir_name/}
file_name=${file_name/\/lib/}
file_name=${file_name/.so/}
PHP_ADD_LIBRARY_WITH_PATH($file_name,$dir_name,TCLIP_SHARED_LIBADD)
else
AC_MSG_ERROR([no result from pkg-config opencv --libs --cflags opencv])
fi
done
我立刻就明白了,Linux上輸出的都是具體的.so路徑,MacOS上都是相對(duì)的路徑,而config.m4中是根據(jù)具體路徑和擴(kuò)展名判斷的,明白了問(wèn)題,辦理就簡(jiǎn)單了.PHP實(shí)戰(zhàn)
將 pkg-config opencv --libs --cflags opencv 的執(zhí)行成果修改為具體的路徑,并替換到config.m4中：PHP實(shí)戰(zhàn)
代碼如下:
OPENCV_FLAGS="-I/usr/local/include/opencv -I/usr/local/include /usr/local/lib/libopencv_calib3d.dylib /usr/local/lib/libopencv_contrib.dylib /usr/local/lib/libopencv_core.dylib /usr/local/lib/libopencv_features2d.dylib /usr/local/lib/libopencv_flann.dylib /usr/local/lib/libopencv_gpu.dylib /usr/local/lib/libopencv_highgui.dylib /usr/local/lib/libopencv_imgproc.dylib /usr/local/lib/libopencv_legacy.dylib /usr/local/lib/libopencv_ml.dylib /usr/local/lib/libopencv_nonfree.dylib /usr/local/lib/libopencv_objdetect.dylib /usr/local/lib/libopencv_photo.dylib /usr/local/lib/libopencv_stitching.dylib /usr/local/lib/libopencv_ts.dylib /usr/local/lib/libopencv_video.dylib /usr/local/lib/libopencv_videostab.dylib"
再繼續(xù)執(zhí)行：PHP實(shí)戰(zhàn)
代碼如下:
phpize
./configure
make
make install
順利安裝完成.PHP實(shí)戰(zhàn)
