Output the absolute value of the inverse transforms as images. Perform a fast inverse Fourier transform on the results.ĩ. Then divide them by the complex conjugate matrix of the Fourier transform of the image.Ĩ. Apply all the steps to change the power spectrum inversely to the filtered results. Multiply the shifted logarithm of the power spectrum by each filter pointwise.ħ. To make a high-pass filter, make the rectangle full of 0's among a matrix of 1's.Ħ. Create a low-pass filter by making a rectangle of 1's, with the dimensions specified by the manipulated variables, at the center of a matrix of 0's with the same dimensions as the image.
Shift the result's zero-frequency component from the top-left corner to the center by splitting the matrix into four equally sized quadrants and swapping them across the center.ĥ. Take the base-2 logarithm of each element of the power spectrum in order to improve its brightness and contrast settings in the display.Ĥ.

To obtain a power spectrum, multiply each element of the transform matrix by its complex conjugate.ģ. Take the fast Fourier transform of the matrix. View photos, floor plans, amenities, and more. Read in the image as a pixel intensity matrix.Ģ.
