Exercise 3, Problem 1

Beitrag von tanne »

are the example pictures created by the same parameters as we should use, i.e. should our solution look exactly the same when we do it right?

The example figures are the results of my quick implementation, but I am not sure they are correct. These figures are just used to let you know how to mark the interest points.

Of course the grading would be based on the correctness of your solution, not the similarity to these figures. :)

Hm, I get almost exactly the same result as on the image ...

As far as I can see I only get ~2 points more on the borders where I think I chose another way of working with the pixels outside of the image ('replicate') in my filter operations.

Unfortunately task 2 of problem 1 still looks different :-(

Well, how do we use plot to mark the interest points?

//EDIT:
Use the "hold on" command.

i have the same results as DVancura: part one looking almost the same as the assignment paper, while part two looks completely different.
anybody else having the same problem and an idea what the problem might be?

My part 1 and part 2 look almost 100% like the images in the assignment. The only difference is that I detect several additional points at the border of the image.
