Section 5.2 - what is "Exercise U2.3"?

In the second step (" 2· Apply Filters To the Image"), at the end of “First step: Get Image Info and Crop the image”, there is the line “Do Exercise U2.3 to test the effects of different values.”

How do I do that? I don’t see an “Exercise U2.3”. Maybe you mean exercise 5.3?


Hello @comm ,

That’s a reference to the Perception course. You can check that course for more details. You can also have a look at the OpenCV course in case you want to learn more about this.

Thank you for the clarification. I see it’s been taken out now, which will help avoid confusion in future students.
