I have an RGB image, have transformed into IUV color space
I = (R+G+B)/3 = f1
U = R-G = f2
V = G-B = f3
Now scale space representation is computed for each f1, f2, f3
Ci(; t) =  fi() convolved with g(; t) .

we evaluate a second moment matrix in the neighborhood
of (x; t)

v = (summation over i) (integral over n) (( H) G dn)

where n belongs to R^2

H is a 2x2 matrix i.e. [ ( Differentiation of Ci wrt x)^2 , ( Differentiation of Ci wrt x)( Differentiation of Ci wrt y) , ( Differentiation of Ci wrt x)( Differentiation of Ci wrt y) , ( Differentiation of Ci wrt y)^2 ]

G is gaussian

I m facing problem in doing the integration part. As I am new to matlab I am getting confused what to use. I am sorry for writing the mathematical part in a very complicated way. I have never posted a question which has some mathematics in it.

Thanks in advance.

There's an integral function... not sure exactly what it is you're asking.

I got my answer, Thankyou ! Its just doing the convolution.
