👉 A cymograph is a type of digital image processing technique that involves creating a 2D representation of images by using a series of waveforms. These waveforms are generated by calculating the amplitude and phase of each pixel in an image, and then combining these values to form a continuous waveform that represents the entire image. In cymography, the waves are typically represented as sine or cosine functions, with the amplitude of each wave representing the intensity of the corresponding pixel in the image. The goal
