As I understand the website mentioned, this is really easy. Just record mouseX, mouseY in mousePressed(), using an array. (I would use a PVector ArrayList).  
You can also automate the process using the openCV object detection. You could change the code of [this](https://discourse.processing.org/t/opencv-update-heaviside-step-function-deriving-parametric-functions-of-shapes-sobel-filter/21931/17) example.
