// FM - frequency modulator
// 2016 Tomasz Sulej, generateme.blog@gmail.com, http://generateme.tumblr.com
// Licence: http://unlicense.org/

// Frequency modulation and demodulation of the image
// process goes in following way:
// - convert RGB into desired colorspace (GS - grayscale)
// For every channel
// - modulate signal
// - quantize and dequantize signal (if quantval > 0)
// - demodulate signal using derivative method
// - apply 3 lowpass filters in a chain to remove carrier (if possible)
// Combine channels and convert back to RGB

// Usage:
// * move mouse X axis - change the carrier wave frequency
// * move mouse Y axis - change bandwidth
// * click mouse to fix setup (click again to release)
// * press N to negate image
// * press SPACE to save
