Detailed Description

ImageViz

SoCartesianToPolarProcessing2d engine

SoCartesianToPolarProcessing2d computes the cartesian to polar transformation.

For an introduction, see:

section Frequency
Introduction for FFT

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

If $I_1$ is the real part or $X$ coordinate image and $I_2$ the imaginary part or $Y$ coordinate image, then:

Module image $O_1$ is defined as:

$O_1(n,m)=\sqrt{I_1^2(n,m)+I_2^2(n,m)}$

Phase image $O_2$ is defined as:

$O_2(n,m)=\tan^{-1}\left(\frac{I_2(n,m)}{I_1(n,m)}\right)$
