Hi all,
I have to highlight the squares in an Image Using the OpenCv . I am trying to implement this since 3 days , but not getting how to do this. Please help me to do this . Thanks in advance .
You can use "squares.cpp" in samples folder to implement that for iOS.(you need to edit this code)
I got it I have squares.cpp file. But unable to integrate it in the Xcode Project. Please tell me. Thanks in advance .
Its pretty simple.
Just pass your gray scale image through findContours method. This method will return all the contours found in ur image.
Then iterate through the returned set of contours and apply approxPolyDP() for each set of contours in the set.
Check if the output size of the output from approxPolyDP is equal to 4.
If yes, then it means that it has found a square/rectangle in the given image.
Hope you got an idea.
