A remote sensing image is acquired from an IRS series satellite. Initially a two-dimensional filter with transfer function \( H(u,v) = \exp\left(\frac{-D^2(u,v)}{2D_0^2}\right) \) is applied to reduce scan line effects. Here \( D(u,v) \) is the distance from the center of the frequency rectangle, and \( D_0 \) is the cutoff frequency. Which one of the following will be the transfer function for the corresponding filter to detect the edges in the image?
