One of my upper classmen has gave me a data set for experimenting with vlfeat's SIFT, however, her extracted SIFT data for the frame part contains 5 dimensions. Recall from vl_sift function:
[F,D] = VL_SIFT(I)
Each column of D is the descriptor of the corresponding frame in F. F normally contains…

i have following pseudo code :
void siftup(int n)
pre condition n>0 && heap(1,n-1)
post heap(1,n)
i=n;
loop
/* invariant: heap(1,n) except perhaps
between i and its parent
if (i==1)
break;
p=i/2;
if (x[p]<=x[i])
break;
swap(p,i);
i=p;
please help me to write…

I'm trying to compare 2 images that are taken from a digital camera. Since there may be movement on the camera, I want to first make the pictures "match" and then compare (using some distant function).
To match them, I'm thinking about cropping the second picture and using SIFT to find it inside…

Hi all,
I am very new in image processing and pattern recognition. I am trying to implement SIFT algorithm where I am able to create the DoG pyramid and identify the local maximum or minimum in each octave. What I don't understand is that how to use these local max/min in each octave. How do I combine…
