OpenCV create_samples 失败

Question

我的 positives.txt 文件中引用了 567 张正面图片，格式如下（假设每张图片只有 1 个对象）：

path num_of_objects x1 y1 x2 y2

当我运行

opencv_createsamples -info ../data/positives.txt -num 567 -w 256 -h 256 -vec training.vec

我收到以下错误

Unable to open image: ../data//Users/jkarimi91/Documents/Projects/kaggle/right_whale_recognition/data/imgs/train/whale_00195/w_2753.jpg
OpenCV Error: Unknown error code -9 () in cvSetImageROI, file /Users/jhelmus/anaconda/conda-bld/work/opencv-2.4.8/modules/core/src/array.cpp, line 3000
libc++abi.dylib: terminating with uncaught exception of type cv::Exception: /Users/jhelmus/anaconda/conda-bld/work/opencv-2.4.8/modules/core/src/array.cpp:3000: error: (-9)  in function cvSetImageROI

Abort trap: 6

这是什么原因造成的？

Answer 1

原来是我的txt文件格式不对；格式如下（假设每张图片只包含1个物体）：

path num_of_objects x y width height
