I'm currently doing a research on Automatic traffic sign detection using SIFT algorithm for final year University project. I am using OpenCV and at the moment I have reached until find Descriptors of an image. I am storing this SIFT features in a list using following code,
vector<Descriptor> m_keyDescs;
m_keyDescs.push_back(Descriptor(descxi, descyi, fv));
Now I want to use this features to compare with a new image and I want to recognize whether the new image is same as the previous image. But I have no idea how to use this features that stored in a list to identify new image. How can I retrieve this stored list and compare with newly created Descriptors of an image??
I am so glad if you can help me as I'm new to OpenCV. :)
I have defined Descriptor class as,
class Descriptor
{
public:
float xi, yi;
vector<double> fv; // Feature vector
Descriptor()
{
}
Descriptor(float x, float y, vector<double> const& f)
{
xi = x;
yi = y;
fv = f;
}
};
Thanks for your kind consideration...
