Hi, I've used the RNG function but it doesn't give me a real random value. I get the same values every time I execute my program. The code I use is the next one:

RNG rng;
int a1;
a1 = rng.uniform((double)0, (double)1)*512;

Can anybody help me?

Thanks in advance

Is there a way to create a matching based on trees and that computes the Cross Checking?

Now, I have two ways to make the matching:

1) FlannBasedMatcher matcher(new flann::KDTreeIndexParams(num_trees));

2) BFMatcher matcher(NORM_HAMMING, CrossCheck = true);

Can I merge both ideas?

Thanks in advance,

Hi,

I'm using the 'drawmatches' function and it works fine. But i'm wondering if i can draw only the matched keypoints with the rich information (size and angle). The flags are: DRAW_RICH_KEYPOINTS or NOT_DRAW_SINGLE_POINTS, but not both at the same time.

Does anyone know how i can solve my problem?

Thanks in advance,

I want to compare the scales between two pairs matched

Hello,

I'm trying to extract the scale from brisk's descriptors, but i don't know exactly how. I've already get the keypoints and the descriptors from my image.

I saw in another posts that I can get the size from the descripor wich is proportional to the scale in this way: size = scale * magnifier) but i need the scale value.

How can i get the scale value? Or the magnifier value?

Can anyone help me?

Thanks in advance,

Ok, thanks!

I was used points2d as keyponts... The problem is solved now, thanks!

Thanks! Could you give me an example about how i do this in c++? I've already tried using "keypoint.angle" but it doesn't work. EDIT I mean, I just add the "types.hpp" in my code, but I still can't use it on my keypoints that I've extracted before with the BRISK constructor.

Hello,

I'm trying to extract the orientation and scale from brisk's descriptors, but i don't know exactly how. I've already get the keypoints and the descriptors from my image.

Can anyone help me?

Thanks in advance,
