Question

我正在尝试运行并检查来自 here and executing its sample.c 的示例程序。我给出它的参数，第一个是 facefinder 的路径，第二个是输入图像，第三个是输出图像等等。但是当我给出所有路径时，它会显示以下错误并关闭。我正在使用 Visual studio 2015 和 opencv 2.4.10

错误：

我的总体论点

E:\pico-master\rnt\cascades\facefinder -i E:\1.jpg -o E:\ -m 128 -M 1024 -a 0.0 -q 5.0 -c 1.1 -t 0.1

OpenCV 找不到写入程序 将图像写入磁盘，因为您没有在 -o 选项中指定图像路径。

使用-o path_to_image保存输出图片，例如：

-o E:\img.jpg
