Detailed Description

ImageViz

SoPolarToCartesianProcessing2d engine

The SoPolarToCartesianProcessing2d engine computes the polar to cartesian transformation.

For an introduction, see:

section Frequency
Introduction for FFT

This engine computes the polar to cartesian transformation or module/phase to the real/imaginary transformation.

If $I_1$ is the module image and $I_2$ the phase image, then:

Real part or $X$ coordinate $O_1$ is defined as:

$O_1(n,m)=I_1(n,m)\cos(I_2(n,m))$

Imaginary part or $Y$ coordinate is defined as:

$O_2(n,m)=I_1(n,m)\sin(I_2(n,m))$
