Hello at all! I must get from an image eigenvalues and eigenvectors to realize person detect with colors. How can I obtain eigenvalues and eigenvectors? The results are as the trace of matrix S where to each color band I use partial derivatives rx, ry, gx, gy, bx, by for the (r)ed, (g)reen and (b)lue bands?

thanks for your time!

Oh so wait, now people just expecting us to solve their homeworks or school projects? First of all, could you explain why you would want to use eigenvalues and eigenvectors at all to do color based detection of objects, in this case persons?

@StevenPuttemans yes people detect. I must calculate S matrix and after its eigenvalues and eigenvectors. But I don't know how I create S matrix as in picture. thanks you

Again, explain WHY you would do it this way ... it is not a good approach!
