Label Contours
Hello,
I post this message because in need help with a project.
I have a binary image that containt object i want to detect ( obtained with a backgroundSubtractor)
Once detected,I want to give each object a label on an other image (the label Image). Then on the next image ( because i use a video ), I want to know which object has already been labeled using the last label image.
I use "findContours" to get all contours;
my Question is : Is there any method or function that could help me to get all pixels of with a given value (for example 3 )? I would like a function like "cv::findNonZero " but more specified like "findNumberPixel".
By waiting you answer i start to try create my own tools.
Thanking you in advance
Solution : (Thanks to LBerger ) Using InRange with all my values allows me to detect the label i want DrawContour with filled option allows me to draw my labels
