Matlab Part, Section 3 | |
Note that in section 3, where you work with natural images, you don't need to repeat subsections (a) and (b) of Section 1 -- since they refer to mathematically defined signals. |
Matlab Part, Section 1, Subsection b | |
Please note the following small but important update in the EXAMPLE for forming the 2D cosine signal in Matlab. The multiplication of the two cosine parts is at the component level using the operator .* (and not just * that applies matrix multiplication and may result in a signal that does not correspond to the given mathematical formula). Accordingly, the Matlab code should be: phi_xy=A*cos(2*pi*omega_x*(x_grid)).* cos(2*pi* omega_y *(y_grid)); |
