AlgoMotion | MIDI Art: Coltrane on Sax Plays Giant Steps #midiart #music #algorithm #computervision @AlgoMotion | Uploaded February 2024 | Updated October 2024, 11 hours ago.
An image of John Coltrane playing sax gets converted into MIDI art that plays his tune "Giant Steps".
The algorithm for generating a MIDI file from a given image is roughly:
1. Run edge detection on the original image.
2. Dilate the grayscale edge image.
3. Downsample the image to a height matching the number of notes in the desired range.
4. Convert the downsampled image to MIDI by constraining the notes to certain pitches over time.

This animated visualization depicts the satisfying symmetry of the functions y = x^n, for n = 1, 2, 3, ..., 10, with the corresponding functions y = x ^ (1/n), for n = 1, 2, 3, ... 10.
The final plot resembles an onion, or a piece of garlic, or possibly some other known physical entities...
