Data Science Enthusiast | Code Junkie | Lifelong Student https://www.linkedin.com/in/andrew-udell-108802140/, # Get the area of the image as a comparison, # Go through and find relevant contours and apply to mask, # Instead of worrying about all the smaller contours, if the area is smaller than the min, the loop will break, # use dilate, erode, and blur to smooth out the mask, https://www.linkedin.com/in/andrew-udell-108802140/, blur: affects the smoothness of the dividing line between the background and foreground, canny_low: the minimum intensity value along which edges will be drawn, canny_high: the maximum intensity value along which edges will be drawn. Adjusting it too high may affect performance, but pushing it too low may miss out on important edges. Are these quarters notes or just eighth notes?
