I am trying to do object detection inside of an image, where I have a template image and search through a larger image for matches to the template. It needs to be rotation- independent, although scale independence is not as important.
Template matching seems to be slow and is dependent on orientation. I think flann based matching will work, and I have started here: http://answers.opencv.org/question/983/object-detection-using-surf-flann/
Can anyone help with how to modify this code? I need to detect object position and orientation, but I don't really need to map or draw the lines.
Using openCV 2.4.7, visual studio 2012.
