Usage
- No installer is needed. Please run FFT2D.exe directly.
-
Prime factor algorithm is automatically used even if "Width" and
"Height" are not power of 2.
You can make a graph in Excel if you save the FFT results as a CSV file.
Example 1: Edge enhancement
Increase high frequency gains with the graphic equalizer.
Example 2: Restoration of motion blurred image
You will find a direction of parallel black lines at the frequency domain.
Then specify the direction and control the EQ so that those black lines
(lost frequencies) are recovered.
