Transforms the FFT of an image or images from a rectangular coordinate space into a polar coordinate space and sums the polar FFT along rho and theta.

Theta Summation—Select this option to save the angular FFT magnitude summation. Enter a variable name suffix in the text field provided.

Rho Summation—Select this option to save the radial FFT magnitude summation. Enter a variable name suffix in the text field provided.

Create New Image—If this option is selected, the processed data is used to create a new image. Enter a variable name suffix in the text field provided.

Overwrite Image—If this option is selected, the current image is overwritten by the processed data.

Discard Result—If this option is selected, the processed data is stored in a temporary variable.

Variable Suffix—If the Theta Sum option is selected, enter a suffix for the new image variable name. This suffix is added to the original variable name.

Variable Suffix—If the Rho Summation option is selected, enter a suffix for the new image variable name. This suffix is added to the original variable name.

Variable Suffix—If the Create New Image option is selected, enter a suffix for the new image variable name. This suffix is added to the original variable name.

OK—Compute the polar FFT and exit the dialog box.

Apply—Compute the polar FFT, but do not exit the dialog box.

Cancel—Dismiss the dialog box without taking any action.
