A code to detect key colours on a spectrography image of an audio file.
This code was made as a show to display the power of OpenCV as a tool to analyse signal. In our case, a spectrograph of an audio file was used to detect a specific colour
After running the code, the red color would be segmented (masked!) and a green circle highlighting that region is shown on the plot as shown below:
You are free to use the code [here] as long as you pinky promise to share your knowledge with me!
