This tool based on OpenCV and CMake. Please install OpenCV and CMake first.

This tool helps me fill the area of positive samples in the picture. Therefore I could regard these picture as negative sample in training.

• Build this project first

mkdir build
cmake ..
make

• Run fillpos and input a path as argument

cd bin
./fillpos [the file path]

An example of description file:

Directory structure:

/img
  img1.jpg
  img2.jpg
data.txt

File data.txt:

img/img1.jpg  1  296 171 52 52
img/img2.jpg  2  100 200 50 50   50 30 25 25

Image img1.jpg contains single object instance with the following coordinates of bounding rectangle: (296, 171, 52, 52). Image img2.jpg contains two object instances.

• Output

Images will fill like this.
