Now, I'm trying to detect the growth of plants by comparing pictures of plants. The camera on a flower pot will take the picture of the plant every hour. I want to my device get heights of each picture and compare them relatively using openCV. But I got some trouble with detecting of plants. How can detects them and get shape using openCV?

You can assume that there are one flower pot and one camera.
The positions of them is fixed.
So we can calculate relative difference of a flower's height from two picture.
