Where there any problems with the homework so far with exercise two, with the three tasks?

I mean, I guess not everyone has started yet, but for those who started, it's really not

that much.

I've discussed one of the topics more or less already in one of the lectures on one of the

exercises.

I also uploaded a new video for that to explain it in a bit more detail, and then a second

video to discuss the exercises in particular, or the exercise two in particular.

So if you have any detailed questions, just look at them.

And today we will discuss a few more exam questions, if my PowerPoint works.

And the questions are more or less based on this exercise.

And you will see there are certain questions that always appear in the exam.

Just to give you a short example, there's more or less always a task where you have

something like this.

Can't I make it full screen?

All right, that works.

That's the wrong image.

Something like this.

Where you have a structuring element for the morphological operations that you have to

implement, and then you have some image.

All right, so we have an image here.

Black is the foreground, white is the background, so it's inversed, the colors, and then you're,

for example, supposed to do certain computations on it.

In this case, a dilation.

For those who have been here, like, three weeks ago when we discussed everything, or

if you've visited a lecture, you should know what a dilation is.

But if not, then I can also discuss it again today.

So yeah, this is just one of the tasks that happens or comes up quite often in the exam.

Like here, for example, this is also a similar task.

I can zoom in a bit later.

But there are lots of tasks where you have to delete or erode something, or use opening

and closing and so on.

So that's something that I wanted to discuss today so that everyone gets full marks on

that in the exam.

Tasks like this usually give around 10 points.

And if you understand how it works, you can do it in a few minutes, and that's like 10%

of the exam.

So it would be a waste to not get full marks there, especially because it's so easy.

All right.

Then let me have to switch between two power points.

I hope it works.

Computer has made some trouble today, so I hope it works somewhat.

So the first thing that you have to implement is the convolution.

I'm just going to repeat it here.

That's the same thing that you have to do in exercise.

Oh, and the first exercise, maybe I will reiterate that part again.

Here we have the convolution task, and it's actually quite simple.

You have to do two tasks, more or less, or three tasks.

You have to do a slow convolve.

Just implement a convolution, more or less.

You get an image, you get a kernel, just convolve it.
