A gesture recognition tutorial- (stories and thoughts) part 2

So after posting the last post, I went to work on the project . I immediately ran into some difficulties regarding some features I wanted to implement. It was during the process of making a webcam feed using a tkinter window and a label. I was hoping to update the label each time a web cam image is captured basically after converting that into a png image by using image write. I suppose I should have known something so simplistic may not work. After all ,so many things are involved and that the higher level functions wont work now.

The problem was that I don't really know how tkinter is implemented in the background ,how it runs etc. I should have explored the libary programs a little bit. I suppose I should research on those library implementations also . I did found another tutorial which will allow me to implement the function I want.

But I want to see the implementation first

But for now the plan is this 

The link to a great tutorial I found:
