Hi,

I did apply one of the key point detector in one image as follow:
I=imread('test.png');
points = kp_harris(I);
the output is : a vector size of <407x2 double>

then I would like to extract the features of the image from the selected points which represent important information of the image using LBP,, 
I do have the sample code for LBP:
 
I=imread('test.png');
mapping=getmapping(8,'u2'); 
H1=LBP(I,1,8,mapping,'h');

this code returns the local binary pattern of the image "test.png", but i want to apply this code to only extracted points? is that logical? and possible?how can i do it?

thanks in advance...
 

hello
even I have to extract features based on LBP.
Can you tel me how you did it.
I am getting a error in the above code.
