Live preview of image frequency domain (FFT)
Following app uses captured frames to analyze their spatial domain (frequency domain or fourier domain). Those are live previewed. You can choose either standard view, frequency or phase. Couple of extra features like rotation, matrix, quality etc.
Only in landscape mode due to opencv.
Mode: Normal view / Frequency / Phase
Grid: 1x1 or 4x4
Camera quality - Lowers the image quality before FFT
Stretch - Stretch the image to full screen or square (native FFT)
Rotate - rotate each cell towards middle (native FFT) or outside
Camera zoom - zoom of camera before FFT
Image zoom - zoom of converted image, after FFT
Flashlight - as the name suggests
Exit - as the name suggests
