我正在尝试运行并检查来自 here 的示例程序并执行其 sample.c .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:

我的总体观点
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
最佳答案
OpenCV 找不到写入器将图像写入磁盘，因为您没有在 -o 选项中指定图像路径。
使用-o path_to_image 来保存输出图像，例如:
-o E:\\img.jpg
