按照http://docs.opencv.org/2.4.4-beta/doc/tutorials/introduction/desktop_java/java_dev_intro.html的说明,我遇到了这个:
让-j8
...
...
链接CXX共享库../../lib/libopencv_java244.dylib
LD:未知的选项:-whole归档
铛:错误:连接命令,退出代码为1(使用-v看不到调用)
make [2]:*[lib/libopencv_java244.dylib]错误1
make [1]:* [modules/java/CMakeFiles/opencv_java.dir/all]错误2
make:***[all]错误2
有什么建议？
我正在尝试对http://docs.opencv.org/2.4.4-beta/doc/tutorials/introduction/desktop_java/java_dev_intro.html中的示例稍作修改
CascadeClassifier faceDetector = new CascadeClassifier("/haarcascade_frontalface_default.xml");
Mat image = Highgui.imread(originalFile.getAbsolutePath());
MatOfRect faceDetections = new MatOfRect();
double w = ((double)originalCrop.getWidth());
double h = ((double)originalCrop.getHeight());
faceDetector.detectMultiScale(image, faceDetections, 3, 1,
Objdetect.CASCADE_DO_CANNY_PRUNING , new Size(w/16, h/16), new Size(w/2, h/2));
来自 API： scaleFactor – 指定图像大小在每个图像比例下缩小多少的参数。
更改 scaleFactor 会更改检测到的内容。例如，对于以下图片：http : //graphics8.nytimes.com/images/2013/04/02/world/MOSCOW/MOSCOW-articleLarge-v2.jpg
scaleFactor 为 3 --> 没有检测到戈尔巴乔夫的脸
scaleFactor 为 2 --> 戈尔巴乔夫的脸被检测两次（一个较大的矩形包含一个较小的矩形）
scaleFactor 为 1.01 ---> 戈尔巴乔夫的脸被检测到一次
这是如何工作的？
