I want to apply Laplace transformation to any `.png` image in matlab, i have general formula which i my professor explained but i cannot figure out what could be values of `k2` and `k1` Here is the formula.
`L = k1 + (k2 * (H)(F))`
Where `k1` , `k2` are any scalars ,i guess and `H` is high pass matrix of given equivalent image an `F` is Fourier shifted matrix of given image.
I have following two main confusion :
- What is `k1` and `k2` and what effect they produce on result.
- How can i apply Laplace transform using given formula to colored image .
Note: I am beginner in image processing i may be wrong kindly point me out and help if you can. thanks
