TP2 - Advanced Functionality 3

[PedroCarvalho98]

Good night Professor @miguelriemoliveira ,

Regarding the Advanced Functionality 3 of the TP2, is there any function to see if the key ('s' or 'e') is pressed and when it's realeased, since waitKey make us wait for a input? We've tried keyboard module and pyglet but we failed to implement them.

Thank you.

Hi @PedroCarvalho98 ,

I think opencv only allows you to check if the key is pressed. As such, you can do the following:

The first time the user presses key "s" the rectangle starts to be drawn and the user moves the mouse around, and then the user has to press "s" again to accept the current position of the rectangle.
