The following is the 2d complex sinusoidal function,
$u_0$ and $v_0$ represent Fundamental Frequencies in $X$ and $Y$ directions respectively.
How can I represent $j$ (imaginary number)?
here is my use-case: ... ... I need to implement Gabor Filter using both spatial and frequency domain equations. In the link ... http://www.cs.utah.edu/~arul/report/node13.html ..., you can see that there are several equations. (14) is the equation of Gabor Filter in spatial domain. (15) is the equation of Gabor Filter in frequency domain. Hence, my question.
